There's one thing that you need to have if you want to keep holding your coins for a long time. DISCIPLINE.
If you have discipline, you can still look at social media platforms and you will not sell any of your holdings whenever you see your coin went up 10% or more. You can still keep yourself updated and you will not think of selling your coins because you're disciplined enough not to do it.

As for me, the Bitcoins that I'm holding since 2021 are the ones that I'm holding until now. Just imagine I'm holding it for more than 3 years already, and yet I still keep myself updated on what's happening in the crypto space. It all comes down to how discipline you are not to make impulse decisions. If you have a long-term plan, stick to it no matter what. If you have price selling targets, stick to it no matter what.

One word, but really helpful for the investor. Being disciplined enough will give you huge profits in the long run.
