I think you'd better buy the top 10 coins. This year's crypto market is very risky. No coin is safe enough. Even Bitcoin has fallen more than 70%, so please be cautious before buying. If you really can't decide which coin to buy, then you should buy bitcoin, which is the best.
choosing coins for investment in my opinion must be with our respective beliefs and most importantly we have to look at the capital that we have because the risks in investing with crypto currencies are very large and require confidence and patience
