Earning 1$ per hour is easy, earning 1BTC per hours is difficult.
Earning 1BTC per hour is pretty much damn impossible. That is making 200 dollars an hour. I don't know anyone making that much at the moment. Basically that is a 600,000 dollar a year job. Not saying it is impossible I just don't see people making that much per hour on Bitcoins.
Well, a big job, or a ASIC mine of 500TH/s would earn that much. That is probably not what most people can setup since that would cost easily 150 000$ to startup But its doable if you can invest it.
Well its a huge ammount to invest and well the roi would be something around 2 years.I guess nowadays there isnt any project able to give you 1 dollar daily,there is the comission on each sale but the sucess need time and investment.The only people maybe doing such is the good and honest admin running some project online.
