I can only back this up. I've been a freebitco.in user since 2015 and have never had any problems! Apart from the server problems that can occur, but have never lead to losing any satoshis. The site might look oldschool and not as trustworthy for most people but all the people I have referred never complained. I moved my bitcoin from freebitco.in to other sites but now I've came back and can say this is the most legit and stable site. I even got into the premium membership (bought some FUN tokens) and I'm very happy.

Keep going freebitco.in !!!! Thanks for all the benefits.
