Bitcoin is just getting started as a new currency and it's successfully attracting people; the number of investers and users is getting bigger, so i don't think that there is risk of investing money in bitcoin at least that's what i think so.
No, in investment wise, bitcoin has a lot of risk, it is other thing that a biggest number of users are here of bitcoin. But instead of it a lot of scam investment sites are here on internet, where majority people everyday lost their bitcoin, and also i was one of them. But now i have opened my eyes and since now i left it all, and also i advice to everyone don't be greedy and don't waste your bitcoin into scammer investment sites.
