IEO doesn't mean a guaranteed profit. 61 btc is a huge amount to risk in just one token.
Price drop doesn't mean scam. It can happen in any project.
A big drop can also be a sign of a manipulations which is more possible on IEO.
OP took too much risk, if you invest it on other coins like ETH for sure you are earning money now. Binance can't help you on this one because they just host the FET token and they regulate it as much, but if the price goes deeper then the problem is within the developer or something shit is happening on that project.
