In the current market situation, I don't trust any cryptocurrency rather bitcoin alone. Bitcoin recovers even after the market crash, unlike many altcoins. Bitcoin is the only cryptocurrency that I can trust because whenever the price falls it will later recover unlike the majority of altcoins that will die. Thus, I suggest you should buy bitcoin and forget about the altcoins at the moment.
I also only believe in Bitcoin because this coin is always chosen by people and there is not too much risk of holding this coin. In fact, you should be afraid of market volatility as we often cannot predict the price increase or decrease so it will be difficult to invest. I personally have used my knowledge to analyze this market but most of them are inaccurate and always contrary to my thinking.
Altcoins are on a downward trend and it is predicted that more than 80% of altcoins will die this year so if you choose to invest in altcoin, your risk of losing money will be very highand will make you feel more depressed.
