there is the free coin technique in this regard, if you put in $100 and the price goes up and you get a total of $200, you withdraw the $100 that you put in at random and keep the remaining $100
so you have $100 free invested and you don't care if it goes up or down, it's a free try
free coin, when I learned it I discovered that it was a really useful technique for making attempts without losing money
I'll do the same with SOLANA, I just need to find an entry point
