Singapore is the best choice if you want to live comfortable, tax free and very friendly to the immigrants, but of course you have to have money for life, good security and stability, and lots of entertainment there
What you mean by tax free?!
If you convert BTC or any other ctypto to FIAT you don't need to pay taxes there or what?!
Well, that fee is very small and I do not think that it is an important issue. Moreover, you can use bitcoin for many purposes without converting it into fiat
