At what amount would you consider moving to a different country to not pay tax on crypto gains?

Hello guys,

Let's say you have accumulate quite some coins and now you are in a situation where you would like to cash out your diamon hands. At what amount of tax would you consider moving to a tax free country on crypto gain? Let's say you are at 30% tax on gains where you live now. Would it be : 50k? 300K? 500K? 1M taxes?

Please add some circunstancies like having or not child or job opportunities and maybe what would be the others criteria to take such decision.

I will start first : I think if i would save 100K on taxe i don’t mind doing it as a single man in my 30’s and leave for 1 or 2 years.

Edit: I live in an European country.
