I agree with you. Why investors have to trust others to choose coins for their portfolios? It sounds very risky. All investors want to earn profits, and in financial games, there are two types of investors: winners and losers. If you are winners, so who will be losers? The people who help you with their advice will become losers, nope, I don't think so. Losers should be you if you naively believe in advice of others.
