Singapore. As an added bonus, no capital gains tax, no inheritance tax, and no income tax on interest income. So your crypto profits that are converted to fiat and put into fixed deposit accounts (or whatever you like), all of the interest income is tax free. Kind of a boring place to live though, but the perfect place to use as a piggy bank.
Here in our country, I can say that although our country is not in favor of cryptocurrency still they are not closing the door, and now we still don't have tax imposed on it so I can say that bitcoin is also friendly here in our country but not yet totally welcoming it, still we are thankful that they are not banning it unlike other countries.
