Here is the list of some countries where cryptocurrencies have acceptance and top of them is Japan is known to have some of the most progressive cryptocurrency regulations in the world.
Switzerland a canton in Switzerland, became known as Crypto Valley after it passed several progressive laws regulating crypto use and related businesses. Singapore, Hongkong, Malta and Luxembourg are also one of the most cryptofriendly countries...
Even there are already a lot of countries that are crypto-friendly, i assumed that not all of them uses and earn money from crypto because there are still people in those countries who thinks that bitcoin and cryptocurrency is a scam or fraud, that is why we still need to comvince them from using bitcoin.
Honeslty, here in my country which is the Philippines, we are very freely to use and earn from bitcoin and cryptocurrency that we also have our own crypto wallet that we can able to pay bills and buy prepaid loads from it, but just like what i have said not all of us here in the Philippines like using crypto.
