But I did not say that I buy only new altcoins. On the contrary, I try to build my portfolio from altcoins that can show good growth and are reliable. Besides, you can make a lot of money with this strategy. You just need to wait for growth and not sell too early. For example, those who bought ETH at 80 dollars in 18-19 could get out too early and sell it at 1000-1500 dollars and its price went up to 4800 dollars.
As for me, at first, who knew it will grow like that, and at second, you need to have a very strong nerves and the power of will not to sell everything when it just starts growing. I'm sure there were many people selling Bitcoin when it reached 100$. But no one could even imagine it will stuck on $20k one day
