fiddy bitcoins

USB miners and fans plugged into powered USB hubs.

Those devices look like erupters which have a hash rate of about 0.333GH/s each, so all up that setup does about 12GH/s.

Currently that level of hashing will net you about $6 day. Sounds like gravy, but there's two things to bear in mind:

1) Difficulty will probably continue going up, which means you make less BTC for the same amount of work. If the USD value of BTC stabilises, you are making less and less USD each time the difficulty rises.

2) That set of erupters probably would have cost $1k+ to purchase. Even if by some miracle you were able to continue making $6 a day consistently, that's an awfully long payback time.

This person is either jumping on the bandwagon without doing the sums, or they have and they're banking on the value of BTC rising significantly in the future.

You need an ASIC device for mining these days and even those aren't going to break even anytime soon unless you drop a decent amount of money.

The rigs I ordered back in August are finally shipping out and should be here Monday/Tuesday next week, even with 100GHS I will be looking at a good 3 months to actually break even with the current difficulty levels, especially as they continue to rise.

people will do anything to not work. When is the bottom going to fall out of this vapor money?

There is never easy money.
