For the moment I avoid new projects, I also don't buy new coins. The only thing I believe right now is ETH and BTC, apart from that coin I am not interested. Holding ETH and BTC is more profitable than other altcoins. If you want to get a quick profit you can trade.
Bitcoin and Ethereum are always the number one trading options in this market because this is the easiest way to make money but requires good knowledge and good analytics in this market. I think any of these traders face a lot of great risks in investing but if they have a smart investment strategy they will avoid a lot of big risks. I not worried about investing but I am always careful about volatility of this market because that is what makes people most afraid.
