Hey, i understand exactly what you are thinking as I thought the same before I invested. I started with $120 and now i'm at $2000! My opinion is this: It's a risk, yes but the payoffs are massive. So only invest a small portion of your Bitcoin that you can afford to lose.
I am more than happy to give you back 7% of your investment if you use my signup referral. If you sign up with my code, I will get 7% of your investment so i'll just send it back to you as BTC. So if you invest $500, i'll give you back $35. Check out my Bitconnect Steemit and YouTube beginners guide videos
