A month after it reached a new all-time high, the rollercoaster ride that is bitcoin continues to thrill and confound after a series of events helped propel the virtual currency to stratospheric new heights, more than doubling its market value with the digital currency now trading at over $70.
Over in Europe, the threat of financial Armageddon gave citizens new reason to consider the viability of cyberpunk alt-money. As Cypriot officials put 100 euro limits on withdrawals, the tiny Mediterranean island will soon welcome its first bitcoin ATM.
Here in the U.S., Silicon Valley venture rich-guys continued to bet on the promise of this burgeoning internet-of-finance disruption, while the department of the U.S. Treasure that combats money laundering, FinCEN, for the first time, issued guidance on decentralized virtual currencies, tacitly giving bitcoin the legal thumbs up but also paving the way for impending regulations.
And quietly in the background, a company called Avalon shipped the first ASIC-based bitcoin miners, custom-built rigs with specially-designed chips for efficiently printing the market’s hottest commodity, ushering in what can be considered the internet’s first gold rush. (Someone recently paid $20,000 for a $1,500 miner from batch two on eBay. At the time of this writing, another auction has a batch two Avalon miner going for over $19,000.)
After opening up its third batch of 600 miners for sale yesterday, customers from around the world from countries like Argentina, the UK, and even Egypt (although the majority of orders came from the big three of the U.S., Russia, and China) made sure Avalon’s units sold out in fifteen minutes. We had the chance to sit down with Avalon’s founder, Yifu Guo to talk bitcoin, mining, and the future.

Motherboard: So how and when did you get involved with bitcoin?
Guo: It was early 2011 when some article about bitcoin popped up in my RSS feed. I don’t remember the exact article but I remember thinking at the time that this was the stupidest thing ever. It would never work. But what kept my attention was that it was open source and after a few days of thought and further research, I concluded that this was legit.
What did you do from there?
At first I just got involved with the community. I didn’t do anything presentable per se, but I participated in some feature discussions, became a regular in the forums. One of my first projects was this website that showed verified physical locations that accepted bitcoins called Bitcoin Navigator. It's still up (sometimes).
What was the community like back then?
The community was very… immature, I’d say. It was mostly tons of speculation. There was nothing really meaningful you could do back then. Mining was the central focus because of the profit incentive. And so a lot of people were just mining these things and so was I. The two long term goals then were to build services around bitcoin while also getting people to accept the concept.
Most of the core developers are idealists, much like the community now. A lot of the people in the community are definitely in it for the money, to get in early and watch the price rise. That’s essentially why it blew up very quickly (in July of 2011). There was no volume, but there was a ton of speculative hype and so a bubble formed.
This time around, there’s still a ton of interest, but there’s also more volume. Every day since reaching the new all-time high, more people are getting into bitcoin. They realize it’s not going to go away. And the people who believed from the beginning never left.
When did things start getting more serious?
I think things were always kind of serious. I would say it really took a turn in September in 2011, when the first bitcoin conference convened in New York City. I went, and all these important bitcoin insiders showed up, like Gavin Andreeson, Jeff Garzick, the entire core dev crew basically, as well as the people running real world bitcoin services. Not [bitcoin creator] Satoshi Nakamoto obviously, but a lot of early people showed up. There was this electric buzz, people talking about the projects they were working on, imagining this bitcoin-powered future. It was incredibly exciting.
"The Holy Trinity of bitcoin is the hardware support, the meshnet for powering the infrastructure free of outside control, and then bitcoin itself."
It was at this time that I started getting to know a lot of the core community. Not the speculators and miners, but people who were actually trying to build out this ecosystem around this idea. I had this sort of epiphany. What I realized was that for true bitcoin adoption, we needed hardware. Tons of software was being developed but no hardware. So I set out to make an Android-powered tablet back then, a simple, cheap tool merchants could use as a point-of-sales. That project is still ongoing, by the way.
Soon after, Occupy Wall Street happened. I knew someone who was doing tech ops and I wanted to help out, since bitcoin and Occupy are, in a way, philosophically aligned. I met someone working on this meshnet project, which was essentially this apparatus that would provide everyone in the area with internet access.
It was then that I realized that this was going to be the Holy Trinity, if you will, of bitcoin, where you have the hardware support, the meshnet for transferring information and powering the infrastructure and services free of outside control, and then bitcoin itself.

This was around the point that I became fully immersed in the bitcoin community. The next conference I attended, in San Francisco, was in March (there was also one in London in late 2012) and by that point, I had come to terms with the fact that this was the future. By then, I had been working on this tablet prototype for a few months.
A month later, in April, I finally had the opportunity to go to China to take the next step and figure out logistically what I had to do to get this thing manufactured. It was there that I ended up meeting one of my future co-founders. That, along with being on the ground in Shenzhen would eventually allow us to fast track our ASIC production when the time came.
"We can’t have a monopoly in mining. It's not very good for decentralization."
From an ASIC perspective, things got serious in around June or July when Butterfly Labs first released their ASIC lineup, which was a big deal. They promised to ship in October, and in a matter of days took in over a million dollars, That, on the one hand, was exciting because bitcoin is progressing technologically, but on the other hand, we were aware of the potential risks. We can’t have a monopoly in mining. It's not very good for decentralization.
So this is when we decided we had to step up and this is when developing an ASIC suddenly became a real discussion. In September 2012, we announced that we would offer 300 units if we could get the crowdfunding to do it. We announced this fully knowing that our competitor would deliver the next month, but that was fine since we simply wanted to get the chips and the technology out there in the wild.
We never intended for this to be a real business. But then lo and behold, Butterfly Labs announced that they were delayed. October came and went, November came and went, December came and went and they still hadn’t shipped. Meanwhile, we’re chugging along.
Then in late January we tried to deliver. Well, we tried. It was almost Chinese New Year and nothing happens during Chinese New Year. Fast forward to now, we’re done shipping the first few hundred units, so we’re 90 percent done with batch one.
This is an obvious question, but why aren’t you mining your own chips?
Like I said, the current reality is vastly different from what we originally had planned. We always figured we would be late to the party. Butterfly Labs and bASIC (another ASIC developer that ultimately failed to launch) were supposed to launch in succession. But due to various complications and delays, it didn’t work out that way.
If they had delivered on their promises, they would have shipped months before our first batch. We wanted to start selling chips so people could make their own units, providing a hedge from a single entity becoming too powerful, and then move onto a new project. That was our main goal. We wanted to prevent this potential monopoly. As it turned out, we became the monopoly we tried to prevent.
You aren’t doing any mining at all?
Nope. Fun fact: none of the Avalon team have their own mining units (outside of test units).
If this was going to be a temporary project, how much longer will you keep the business going?
At this point, we’re going to keep making them until we run out of funding, now that bitcoin mining will continue to be “a thing” rather than not. Of course, everything changes when our competitors eventually deliver. And then we will see what the situation is and go from there. The short term plan is to push for generation two chips as soon as we obtain the necessary funds.
Batch one was $1,300 and batch two was $1,500. At a cost of 75 BTC, batch three units effectively cost ~$5000. What gives?
Well, one of cofounders commented on that, and the main thing is trust, which, since the beginning of the bitcoin movement, has always been the most valuable resource above all else. The first batch could have been a potential scam, so we had to price it at $1,300 (which is the same price that Butterfly Labs has been offering).
"If we wanted to maximize our profit, we could charge much more. For us, this has always been an ideal-oriented problem, not a business-oriented one."
We’ve had plenty of opportunities, such as keeping the technology to ourselves and simply mining, but that was never our intention. So how much is that trust worth? We think it’s worth $5000 by itself. Beyond that, the calculation is based on the current difficulty rate so that break-even point occurs in a month. Which, by the way, as an investment vehicle is a fairly unique proposition. It should be mentioned also that the cost of the batch two was also 75 bitcoins. That the exchange rate has moved is out of our control.
And in the end, this was never what we wanted. If we wanted to maximize our profit, we could charge much more. For us, this has always been an ideal-oriented problem, not a business-oriented one. This is one of the primary reasons we aren’t clearly in the black.
We’re lucky that we held onto the second batch of bitcoins because if it weren’t for the appreciation, we would be very, very deep in the red, which ultimately still isn’t that big of a deal. But batch three now gives the project monetary sustainability, especially since we need to purchase an SMT machine (a pick-and-place machine for mounting devices onto circuit boards) to produce our generation two chipset.
Okay, so now you’ve started shipping your ASIC systems, but as more people get the same miners, the machines become less profitable. Does it really make sense to dive in, for such a premium, this late in the game?
The whole risk/return calculation is detached from fiat currency. The loop has been closed. It’s like any other investment, part mathematics, part faith. Difficulty is not going to skyrocket by multiples of fifty or even ten.
No one can predict the future. We don’t know if Butterfly Labs is going to ship or how fast they’re going to ship. In the end, the price is based on a break-even formula of one month. After that, if you don’t think this is a profitable endeavour, then please, for the love of God, don’t buy from us and stop complaining.
Basically, as more people get into mining, everyone makes less money.
Yes. This is the gold rush. It’s first come, first serve. In reality, the first have come and have already been served. Batch one and two was where it was at.
So then what’s your advice for a prospective miner that’s been recently seduced by all the bitcoin headlines? Is it too late to join in on the fun?
[Points to t-shirt above] In reality, if you have bitcoins already then, I think buying a miner is kind of cool because it’s not only about making money. If you’re here for short term profits, you should stick to day trading.
Mining is sort of magical. I remember hearing a story at a team meetup in Beijing. There was this miner who had moved from Brazil, and he basically expressed that, sure, this thing is making me some money, but what it has really done is changed my life. He couldn't believe that this was real, mining around the clock in front of his house.
"Eventually you’ll be able to hook it up to APIs where it will automatically order your groceries for you."
This machine liberates people. Suddenly, you can figure out what you want to do as a human being because it takes care of your living expenses. Eventually you’ll be able to hook it up to APIs where it will automatically order your groceries for you. It’s crazy but it’s going to happen.
If ASICs are the technological pinnacle, what’s next for bitcoin and mining?
Of mining’s technological evolution? Yes. In terms of major technological developments, it will be a while. What’s going to happen is that there is going to be a die shrink in order to reduce power consumption and increase speed based on smaller gate sizes. Eventually we’re going to reach the theoretical wall because of physics. The atoms will be too small. I don’t know when that will be hit, but the sooner the better.
If bitcoin is a $1 billion market, and it only takes less than $1 million to secure the network right now, that’s not a lot of money for someone to try and take over the mining scene. The faster the technology progresses, the more secure the network is, because it will be that much harder for a malevolent entity to mess with the system. We want to reach 14 or 10 nanometers as soon as possible. IBM/Intel is playing with 7 nanometers right now. The sooner the better so we’ll never again have this scenario where one company like Avalon essentially controls more theoretical computing power than the entire network’s hash rate. This will never happen again.
So inherent technological security?
Yes. Then we can feasibly protect the network based on predictive production and performance. At some point quantum computing might show up, but what is really next? Nobody knows.

If this was never the plan, what’s next for Yifu Guo after Avalon?
Besides ASICS? I want to finish my tablet. I don’t like to build services, I like to build platforms and infrastructure. I want to build a tablet that’s open source. Apple has done a great job of convincing us that technology is expensive when what they’re really selling is a luxury good. Everyone has an iPhone even though it’s essentially a luxury product. They’ve turned the smartphone into jewelry.
Which is fine, but we want something that works but is also cheap. We’re talking really cheap. We want to cut costs tremendously and offer a $100 tablet that is as good, spec-wise, as the Nexus 7, by cutting out all the middlemen. We have access to manufacturing and engineering, and eventually we’ll have our own factories so there will be very little overhead.
What about bitcoin? Where do we go from here?
I think bitcoin still needs more acceptance and the next major milestone is mainstream adoption. Adoption is a natural organic thing that can just happen. Bitcoin’s core features–ease of transfer and production without middlemen–will always give it value.
"How can we take bitcoin’s strengths, its cryptography, its decentralization, and how do we utilize and leverage this model?"
That’s why we don’t really care about its exchange rate. We don’t look at it like a stock, we look at it like technology. It’s a platform. How can we take bitcoin’s strengths, its cryptography, its decentralization, and how do we utilize and leverage this model? Whatever business you’re running right now, add bitcoin to the equation and you’ll see instant profits.
What do you think is the root of all the uncertainty?
People need to get their head out of the sand in terms of thinking of it as a competitor to their local currencies. We no longer live in a localized economy. We live in a globalized economy and bitcoin is designed for a globalized system.
If bitcoin is useful and it has true staying power, what’s the big picture story here? Why does it matter?
Bitcoin is an enabler based around the ideals of peer-to-peer, open source, and decentralization. That’s the future and bitcoin is the vehicle that will take us there. It takes the banks and the humans and the Federal Reserve out of the equation. Without those institutions, we can do things more freely and easily. It allows us to get things done without all of the friction, and whatever we do will be built around these ideals.
How will the recent FinCEN guidance affect mining?
I am not a lawyer but the way I understood it, people who mine are not going to have a problem. Mining pools (organizations that allow users to contribute processing power for their share of the bitcoins) might have to deal with certain regulations, such as applying for licenses.
For individual users, it should be okay, since apparently, using bitcoins to pay for goods and services is fine. Once you have the intention of turning that into dollars or some other fiat currency, then problems might arise. Ultimately this is simply guidance. Our motto used to be, ask for forgiveness, not for permission. But recently I came to terms with an even better maxim, since we’re technically not doing anything wrong. Act and defend your position. And our position is bitcoin. We believe in it.
"It’s not about how much bitcoin is worth. The exchange rate is irrelevant. It’s about the concept."
And ultimately, I think the recent guidance is arguably good thing since it finally offers clarity. This kind of verbiage means that certain organizations can now start accepting bitcoins with more confidence knowing that the government has essentially given virtual currencies the official okay. This be a major jumping off point for mainstream adoption. Exchanges have been following the rules anyway knowing that regulation was inevitable so for most companies, there isn’t a whole lot of change.
What could the government conceivably do to bitcoin then? What’s the worst case scenario?
The worst case scenario is that they attempt to destroy bitcoin itself, and there are numerous strategies they could use, which we don’t really have to go into. But the point is, the idea will never die. Even if bitcoin dies, an alternative will arise, one that addresses the vulnerability that was previously exploited. Then you get bitcoin 2.0.
Which again, it’s not about how much bitcoin is worth. The exchange rate is irrelevant. It’s about the concept of a peer-to-peer ledger keeping system, which so far is working swimmingly. And I think the best example is BitTorrent. They’ve spent billions fighting it and failed. BitTorrent is still rampant. Meanwhile, legitimate companies are now finding uses for the technology.
