I'm skeptical about these claims of countries becoming "bitcoin hubs" (whatever that really means), because it seems like I've heard this story before and it just sounds to me like they're trying to ride the wave of something very popular but without doing anything lasting or even meaningful.
It's kind of like how every business and a lot of altcoins are jumping on the NFT bandwagon to attract newcomers, which I think is complete garbage--because IMO NFTs are complete garbage. We'll see where Singapore stands with bitcoin in five years, because that'll show whether they meant what they said, and only time is going to determine that. Right now it's just a lot of words.
The main reason for that is the fact that we have seen a lot of them claim something like this before and fail, and since we saw them fail before, that ends up causing us to not believe that they would do it now. I do agree that it is not going to be easy, but it could be done. I mean maybe it hasn't been done before, but if you do legal leeway, like not force them too much and very low taxes, or even no taxes at all then it could work.
But, you also need to make sure that you help them out. I do not know how, but convincing them to change the nation they are in and go to Singapore is a very hard ask, so they need to give some incentives as well to make that work as well.
