many people are sorry for starting too late even though they already knew about bitcoin and still didn't believe bitcoin at the time, I also did it but I never regretted it.
I am very sorry when I was in a hurry to sell coins that I had in the past I did not care about the price in the future, even if I keep my coins a little longer I will get a lot of profit, panic sell, yes, that is my regret when I started trading on crypto.
