Haven't done any investment to bitcoin related companies however talking about belief on bitcoin i am holding some bitcoin which i can have and collect or in some cases what i can buy. I think the current price is still good entry point to get atleast 50% profit within a year which we can't get in our local banks.
i havent any BTC in my wallet now...but when i got 1 or 2 BTC in my wallet i will invest all of them in some good company...to get some earning from them.
