I am in favor of a low-tax policy, mostly because in general politicians do nothing more than increase spending that in most cases is unnecessary. I think it's fine to pay taxes for the state to build/maintain roads or help the underprivileged etc. That said, as I believe that much of the money I pay in taxes is political spending that should be dispensed with, I support everyone trying to pay as little tax as possible, especially in a legal way.
In my case, my Bitcoin holdings are not life-changing, so I am not considering emigrating or anything like that, but maybe in a few years I will consider it. There are many things to consider here: in certain countries it is not enough just to emigrate to avoid paying taxes, you have to acquire the nationality in a new country and renounce the nationality of the country of origin, otherwise, you will be taxed anyway.
In other cases it is useful to simply leave, but you have to take into account the factors of each one, if you are very rooted in your country of origin, with your family and friends, maybe it is not worth changing your life just because of more money.
I checked the link for The Nomad Capitalist and of course I was interested in who is in the team, and I must admit that I was quite surprised that except for the CEO and another male member, all the others are women from Serbia (it is easy to conclude by name and surname). Apparently Andrew Henderson really liked it there, so he decided to surround himself with women from that country.
This is a bit off-topic but when I see him the way he speaks, I always think he is gay (I am subscribed to his channel) . The only think that makes me wonder is all those beautiful women around him.
