There is no trusted sites to invest bitcoin.
What?
How can *you* say that? Nitrogen sports is a highly trusted site and you don't know another highly trusted site as just-dice.com with its investment option. I can't believe this...
The only reason I don't invest on just dice it's because I need to buy the alt coin to do it. And we never know what can happen during a long term investment. BTC can skyrocket, CLAM price can fall... But for gamblers who deposit, withdraw fast and exchange the coins to BTC again looks it's good.
