So I was trying this site in which you can win free bitcoin by doing spins just like you would in a slot machine. You win around .000003499 btc if you get a match in which i calculated more or less 1 in every 20 spins. I've been diligently saving and mining for spin so I can get ti 0.03 BTC which was the minimum to cashout. After a month, I got to 0.02 BTC which was like 2/3 of the target.
Much to my surprise today, they raised the minimum threshold for cashout to 0.035 BTC. I was really hoping to cashout before Christmas but I guess that not happening. I'd kill me too if they raise the minimum again once I get near the target.
My friends keep telling me the site is probably a scam but I saw a few people cashing out in youtube. Well I thought I'd give it a try. Free bitcoin is still free. If you want to try it, you can click this link to know more. I'll update this post if I eventually cashout or not.
