First MtGox disapears with an BTC fortune and then Neo Bee. Besides them, there are countless mining companies that never refund their clients on empty promises. Sadly, in generall there is to much scamming going on in the BTC to get this mainstream! Noone want to get ripped off. Especially on his/her first encounter with BTC. And sadly, right now, too many people encounter a scam as their first encounter with BTC.
