Bitcoin is freedom. Do not sell your freedom. Hodl it until fiat becomes less popular than bitcoin. Give it to your grandkids if you have to. Do not sell your freedom.
But what if selling it is going to get you freedom? Freedom to own a house, a car, a yacht, and to have more money? and those things were just a dream to you before but because of Bitcoin, you can finally obtain any of it and much better if all of it at once? I am not against with anyone, I am also a long term holder but I think that all of us have their own selling prices and once it has been reached, we might sell 20%-90% of it but will still hold to have some remaining.
