I absolutly agree with U. I had purchased my first btc sats during 2017 ATH. As everybody, I lost a lot of money so I had quit. Years passed by and I have totally forget about the whole crypto thing until one of my friend made a 100X in crypto. So I bought btc and other cryptos again. As you guess, it was 2021 ATH. Now I am learning and acculomate more for the next bull run
