yes very true..now a days many site operating in the name of bitcoin mining. ..and also many comming up with bitcoin generating software....i pity people dont know that bitcoin is mined with hardware and not software.....gone are the days of revshare, matrix, cyclers...now the word mining is trending.....even long back a company nameed hashocean was mining for 2 to 3 years and suddenly closed down ,even they used to give free 10gh/sec free..... im mining with hashflare for past 22 years and still mining and getting payout...the top 2 companies i trust for mining bitcoin is " genesis mining & " hashflare".... all the programms stating %% will go good until the admin fills his wallet....then will shut down one day....take care . invest only how much u can afford to loose...cheers
