I just wanted to share my opinions on those USB block erupters you can buy on amazon for 50$. Most of them generate around 333mh/s. Here's where my opinion starts. These are completely stupid and absurd. Do the math, these will never ever pay themselves back. Why the hell would you buy some random USB thing that gets hot for over 50$, and then have it never ever pay for itself. Do the math. Right now they make about 16 cents per day. In theory, if the difficulty and price stayed the exact same, it would take 4 years to make that money back. Of course there is the difficulty changes, so in a year that will probably mine absolutely nothing, maybe less than a cent a day. This would never ever pay for itself, so my advice to the people that are thinking of buying this: STAY AWAY
Dam never seen a post like this before you must be a genius.
lol, this +1
