I thought you are really willing to give me 10 BTC lol. Well if I have 10 BTC since I am a gambler, I would use it in playing dice sites but you have stated it already that you want an investment and not gambling. I don't want to suggest an investment sites or group because when it becomes a scam, you  might have put the blame on me so I'll just give you an advise. Don't put your btc to those investment sites that provide an hourly return and promise  a very high return on your investment because it is more likely to runaway in the end so just be careful and research about the sites or group where you want to put your money.
