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?
the thing that I regret the most is that I learned about crypto late than my friends. My friend invited me to buy some bitcoin and told me to save in the long term but at that time I didn't care and didn't want to know it, and right now my friend got a very big profit while I was just learning.
