Just focus on a reliable coin(s) such as BTC or ETH. It takes some experience to play well in this market since it's all a matter of winning and losing.
Through experience you will know who are those person you should trust. But crypto currency are most likely a gamble thus risking your investment whether they win or fail in this market. Since there are lots of factors that a coin may win for now but would gone after a couple of week so it's all a matter of risking or gamble.
The truth is in any type of investment, whether it’s in crypto or out of crypto, we should only trust our own self. That is to avoid the chances of getting scam, and just focus on working our investment based on how we understand it, and based on our own experience. And most importantly, focus on bitcoin.
