But i'm interested in the actions of those who bought their bitcoins more than 2-3 years ago and sold them now or are still hodling them
How did you find the strength and patience to resist this temptation?
I've been holding Bitcoin ever since 2019 and even though I've been sold some of them through the years, I've been constantly keeping some Bitcoins as well.
I also have the opportunity to sell all of my Bitcoins way back in 2021 where everything was on it's peak, but didn't do it for some reasons. Turns out that it would be my worst decision in my investing journey because I could've sell all of my Bitcoins and bought the year after where everything was on it's bottom (bear market)
I'm still holding all of my Bitcoins until now, and I've been planning to sell them during the bull run possibly next year or at the end of the year. Strength and patience to resist this temptation? It's the discipline that will help you, and you will not learn that just by watching videos or asking opinions here. Experience, and adjustments will help you gain that strength that you're saying and it will also help you not to get tempted to sell your holdings whenever you see Bitcoin's price going up. Discipline is the key.
As for your question (subject title), I'm doing both. I'm currently holding some Bitcoins but at the same time, selling some of it. I will go all out and sell all of my Bitcoins after a few months that's for sure.
