If I can figure out a way to do it without KYC, I would sell several times as it crossed points like 100k, 150k, 225k and so on.
As holders we should hope that other holders are in a responsible place financially. That means operating with an asset allocation scheme such that we sell on the way up and can buy when it falls.
If you have fiat and bitcoin, each time you go to buy something you should think which of these am I overweight on compared to my preferred allocation. This will naturally lead you to sell high and buy low. Easy.
