It doesn't matter the current tides, cryptosystem has come to stay. I'm seeing more countries adopting it this year.
I don't know which countries adopted the cryotocurrency.
But many countries are against cryotocurrency in my knowledge like South Korea and Bangladesh are already banned cryotocurrencies.India is under serious discussion about bitcoin usage in their country.But it is good that many people will come to know about cryotocurrency but their respective government needs to regulate the cryotocurrency rather than totally banning them.
