My greatest crypto regret was when a friend wanted to give me 6btc in 2010 and i told him this 'you are just wasting your time with all this useless internet things' and even the guy wasnt sure if what is holding will worth it in future so the guy replied 'it costs me nothing' ,after few months i stop seeing the guy again even till date,i thinks he is not in my city anymore,what is your greatest crypto regret?
You would have also regretted not holding the 6 BTC if you had collected and impatiently sold it. It takes a lot of discipline to invest and hold Bitcoin/Cryptocurrency long-term.
Regretting things is a waste of considering there are lots of other investments that could make you rich long-term. I bet if you are shown the investments they wouldn't make sense to you
