I would only buy few coin like BTC and ETH because we need coins who have been proven to be working. If new coin comes, yes, maybe we can buy like BNB but I would wait to be really proven. Many coins did fail like Tron, Nano or EOS. People said buy, but it was completely fail. People forgot to do DIOR. Most coin is useless such like Litecoin, EOS, TRON, DOT or XRP. Same tech different layout.
