Immigration is very much tough issue to discuss. People think govt are designed to serve them free despite not paying taxes. And so they tend to push for communist and socialist regime and stay broke forever. Ever since EU and US immigration issues are coming out many nations outside have realized that they should only give citizenship to skilled labours. Be it engineer, scientist, tech and other medical etc people.
El Salvador that came into light after adopting bitcoin as one of their legal tender has started issuing 5 K passport in their program. Where they are taking the skilled labour.

As you can see from the tweet. The immigration is strictly for the highly skilled and the known people. And that goes to show that they are building the value on the island. And this also keeps the quality of the immigration. In short there would be massive chances of the similar policies used by others in the market. And so people who use religion, controversy etc for immigration won't work anymore. World is not supposed to help out every random person because they are victim as the approach never worked in EU and the US for reason.
Bitcoin based nation, and quality of life improved due to such national policy would also improve their national value in the grand scheme of things. You can see how the El Salvador would openly get managed by other cryptos too. So such places getting the blockchain future is something to watch out for as well. Let's see what other nations do with such policies.
As we know miners are moving to the El salvador and their resources are being used so there is a chance that blockchain based nation of the future would have El salvador in their data.
