Anytime the price of an asset or commodity shoots straight up vertical producing 10x+ returns, it's a good time to sell.
Let this be a lesson to anyone new to crypto, not to get greedy.
You can say that bitcoin was 10x return a year back and it was a good time to sell. But do you remember when bitcoin was at 69,000$, the whole media, everyone was shouting for 100K bitcoin? At that point, it was hard to sell when everyone was anticipating 100K.
You can call this greediness, but these whales make such an environment that a common man like us never sells and keep holding.
So are you regretting that you arent unable to sell the coins at that time? I mean who knows what gonna happen in future. You can only say anything based on luck. I myself had bought Bitcoins at 50k usd and right now holding it. Does that make me impatient? Nevertheless coming back to OP, its really great to see that BTC has impacted a lot in many peoples life. Definitely I can proudly say that after 3-4 years when BTC will be at 100k usd or more, people will recall this time and will frown that wish they had bought Bitcoins in the bear market when BTC was around 20k usd. Lets not expect more and wait to see what happens next.
