Actually if you can do the analysis well, then buying 3 coins with 1 Eth You is the right way to get bigger profits. instead of only storing 1 coin Eth. Because if we find a good coin, and at a low price. then it's not impossible that the coin can experience an increase in price to 20x more expensive or even 50x more expensive than the first price of the coin appeared. Just imagine how much profit we can get.
