i believe it would all depend on the performance of the coin, how many do i hold and for how much did i get it so it’s difficult to put a specific number on it because of factors aforementioned
personally i would like to have the maximum profit a coin can offer you just have to make sure that you can sell at its peak right before it crashes
If you plan to let it crash into nothingness, that is, to abandon it at some point, why bother getting into it in the first place?
The ideal is for your family office or Corp or Civilisation to end up with all the coins anyway, since ultimately money is IOUs, and the value of IOUs comes from the assumption that they will be "redeemed".
So if it crashes that just means you just bought them back cheaper and cheaper and cheaper until at the bottom you got them almost free, and if you check how much some civilisations pay for paper or specie to use as tokens for their IOUs aka money, all you need do to stay ahead in the game is have that bottom be not too huge a price per token to pay for tokens you can use as IOUs aka as money for your own civilisation or Corp or family office or just as personal IOUs among yur peer groups or whatever.
If you aren't prepared to back a money, don't waste time and effort on it.
