i think almost all of investments is scam

after they get at they're quota they will become a scam like other investments scam :3 i think that we can't risk at investments because they will stole your btc

they will let you profit low and they will get your high balance.
Yes specially in bitcoins mostly all of the investement schemes are scam if not all.And its better not to invest anywhere your bitcoins and just to hold or either spend them in different places rather than investing in ponzi and scam sites which gonna run with your money one day.
I do not think so. however, it still better to invest rather than only holds bitcoin. it is depend on where and how do you invest your bitcoin. do not invest in HYIP or any site that offer doubling your bitcoin without do not do anything. but there are some investment that no scam in it, trading is the best way. If we have a lot of knowledge, good strategy and capital, we can earn a lot of bitcoin every trading. I am not trading bitcoin everyday, I just do it when I am feel it is the right time to trade.
So apart from trading sites which is the legit place to invest your bitcoins? None I guess and you are saying that not all sites are scam and at the same time you are excluding hyips and doubler sites so what else left for investing bitcoins? And if you have any genuine sites to invest bitcoins from where we can earn profits then you can share the links we will be much interested in knowing those sites.
