Ever since I've been into crypto I've been hearing two big scams are in crypto. One being Bitconnect and the other being Tether. Bitconnect looks like the ship is sinking, and Tether looks like its day may be coming as well.
I myself have never used it, but it seems foolish to even assume that you can put your money somewhere that isn't volatile in crypto. One of the great things about cryptocurrency right now is its volatility anyway. Trading back to Bitcoin when you want to exit with profit (and even tracking profit in BTC) has always worked just as well.
