Smart Trade COIN (STC)

Hello everybody, do you have any experience with this site? I invested a small sum of ETH for the beginning and I see some big profits, so I am not sure if it is really that legit as everybody told me (friends). I also created a subreddit (r/SmartTradeCoinSub) for it so if you are also using Smart Trade Coin or you were/will you are free to join to have a discussion.
