(Note: Since most HN readers are technical, this comment is being downvoted by bitcoin enthusiasts among them. You won't see many replies from them to this comment, since their reaciton is political and not a technical statement. Still, I'll keep it up. This comment is currently at -2.)

To put this into context, by comparing it with a centralized version, an equivalent number of actual transactions could be done at a bank with a crud app running on a $5 complete desktop PC which the Raspberry Pi foundation just released[1]. It is a 1 ghz computer with 512 MB of RAM. It draws up to 0.7 Watts.

Wait, wait, wait. did I say an equivalent number? Since Bitcoin is limited to 7 TPS (7 transactions per second), I should modify this to 100x more transactions (700 transactions per second), if you wrote it in C, or if not a hundred times, then at least ten times as many in python. If it were a crud app running at a bank, a $5 computer could do 100 times the transactions that 650 Phash/s of wasted effort collectively give. And 40 megawatts.

Bitcoin is a supreme waste of resources through the proof of work hack. It is like emulating a GPU in a CPU...in javascript. I mean, sure, you can do that. You can run Open GL by emulating a GPU in single-threaded Javascript.

But it's a stupid, wrong solution. The basic idea sucks. It's bad.

(by the by my target price for btc is $600,000 based on a comparison with how bad gold is physically, and the market cap of gold. :-P.)

I love fiat currencies, they're one of the great achievements of modern civilization. (This sentence isn't ironic, it's actually how I feel.) Despite my target price I don't hold any bitcoins at all. I hope some of the numbers I've given can put into perspective why.
