Most times as humans we feel more regret for the action we didn't take than the ones we took.
If the current Bitcoin price is the lowest and continues to surge to a high level, of course it is all the deepest regrets, but if the price of Bitcoin drops deeper deeper, of course the umpteenth time.
But at least we can still do activities in the crypto market by conducting trading or investment in the long run, if we believe in the price of bitcoin can penetrate $ 1 million.
For me in the crypto market there is no regret while you believe and the pahan with the way it works Bitcoin.
