Up, Up, and Away! Cryptocurrency Optimism Files High

Shaking off an endless stream of frauds, thefts, arrests, and convictions; ignoring warnings and regulatory stop signs; and even blowing through the minor glitch of a catastrophic and fatal fatal fork of Bitcoin; the cryptocurrenty community cruises to new heights of techno-optimism.

Even supposedly rational capitalists seem to be carried away.


For examplet, NVIDIA corporation is have another good year, driven by the sales of GPUs. (All alums of Illinois are proud to see how important these descendants of the much laughed at Illiac IV have become.)

Jen-Hsun Huang, the CEO of NVIDIA, recently expressed glowing optimism that GPUs will continue to grow not only for graphics but also for cryptography and cryptocurrency mining.

It’s hard to say what fraction of the $1.9 billion income is attributed to cryptocurrency, though the total amount of Bitcoin mined in a year is less than $200 million. No matter how you slice it, cryptocurrency alone cannot really support a billion dollar hardware industry.

Nevertheless, these results do show that, while cryptocurrency may not be benefitting the world or disrupting money quite yet, it certainly is sucking down computing resources and the requisite electricity to run them.

Overall, the huge GPU industry is sustained by completely imaginary and economically inexplicable activities—such as video games, digital television (including porn), and, evidently, the scratch-off lottery of cryptocurrency mining.

NVIDIA’s Jen-Hsun Huang believes that cryptocurrency and blockchain are “here to stay” and will continue to be an important market for GPUs.  I have to wonder about this prediction. It’s far from clear that the current exuberance is rational, and with the catastrophic forking and reforking of Bitcoin, one wonders when the bottom will drop out.

We also should note that much of the market for cryptocurrency equipment is driven by and dark markets. These folks may remain a robust consumer base for NVIDIA, but it’s hard to see that as a great thing for the world.

Even more important, as quantum computing comes online in the next decade, GPUs will no longer be the top of the line. QC will be overwhelmingly faster, and GPUs will be next to useless for cryptography or cryptocurrency. That means that even if cryptography and cryptocurrency continue to grow, they will no longer be using GPUs, and certainly will not pay premium prices for them.


On another front, the Blockstream company has literally left the planet, with the launch of the first of many satellites designed to make Bitcoin available everywhere. The stated use case is Africa and other places with poor Internet access. In particular, you can’t run a full node (let along a mining operation) without significant network bandwidth, so Bitcoin isn’t fully available in many places.

I think the idea of this scheme is to provide a dedicated satellite network that connects Bitcoin nodes into the global net with relatively low cost ground equipment. This base station would be pretty much dedicated to Bitcoin, and connected to nothing except other Bitcoin nodes.

I have to wonder what use such a node would be to anyone, especially if the ‘last kilometer’ is marginal. I also have to wonder how this could possibly be financially viable. Space programs are obscenely expensive, so this doesn’t seem like the path to low cost connectivity on its face. We’ll see.

I will note that the general scenario would be that with this inexpensive ground station, “you could be transacting globally with bitcoin”. “Transaction globally” means “moving money offshore”, which is probably of interest to some people in Africa, but may or may not be a positive for the local economy and society. Again, we’ll see.
