It's impressive to know how Bitcoin's price started. I have this regret on why I didnt know or bought Bitcoin on its earlier stage. But even I bought Bitcoin back then at cheaper price (2015), im still not confident to hold it for long period and was tempted to sell at low price after seeing an improvement, not knowing it can increase further. Hence I failed to hold longer. So asking me now how does it feel? I still have regrets but there's no point on dwelling in the past. Thus, if you dont want to miss the same opportunity again, dont repeat the same mistake since you're already aware of its history.
