Those who thought it's too late to buy bitcoin when it was over 50k can see how much Bitcoin has gained in less then a year.
Sometimes it's blessing in disguise that we forget things we have in our custody like Bitcoins. But Bitcoin and just forget them (without losing the keys)
It's never late to start up anything, what is important is been able to start small and grow gradually as time goes on everything will fall in place so in this context buying Bitcoin is never late and I think it's better of to buy earlier and hodl and before you know it your coins have resulted in profits that you won't expect, just as you said over 40%profits that's awesome. Sometimes i take up this pattern usually when I want to save up some money, I put them in an account that I won't have access to it's password and other requirements and before I know it, have saved up so much.
