Not having a bitcoin is not the reason to step out of cryptocurrency coz there are lots of potential coins and tokens out there. I did not own any as i had to sell it way back 2017 but it didn't stop me to be here coz i own ETH, BNB, XRP etc. If you lose, stand up and change your strategies. But leaving crypto is a choice, i just wish you would not regret it in the following years.
