A Bitcoin miner in every hand
Instead of spending $1 on something, you can burn $5 of electricity! Suppliers figure you're more likely to waste some energy than you are to type in a credit card number, so they say go for it.<p>And as the big ASIC miners get more efficient, your device will generate even less revenue. In two years, you'll be running at a small fraction of the chip's original mining rate, but still wasting just as much energy!<p><a href="http://media.coindesk.com/2013/09/bitcoin-difficulty-graph.png" rel="nofollow">http://media.coindesk.com/2013/09/bitcoin-difficulty-graph.p...</a><p>I'll pass, thanks.
