Tax free, crypto friendly who wouldn't want that, seem like the perfect place for crypto lovers to reside on, more people will take advantage of this but I hope this is not just a bait offered to lure people in before they will have a reason to change this policy, I hope the government has a strong source of generating revenue because tax plays a vital role in that aspect.
You bring an important angle to the discussion, there are people that are rich enough that they can decide where to live in order to save on taxes, however one of the most important aspects is the stability of the jurisdiction where they want to live.
After all even if things are attractive when it comes to the taxes other aspects need to be taken into account, like the weather, the standard of living you can expect on the country and the political stability of the country, the last aspect is key, after all, you do not want to go through the trouble of moving to another country only for the laws to be changed while you are there and then you will have to pay huge taxes because of it.
