There will be countries who'd surely oppose the rise of cryptocurrencies since it combats their best interests and there would be those who'd openly welcome it since it helps them do things for their citizens. There would be a mixed reaction about the rise of cryptocurrencies that's for sure, but given the positive reception cryptos are receiving right now, the future seems to be bright. Numerous countries have expressed neutrality or openness about the cryptocurrency fad which is great, while a few ones expressed negativity since they can only see the bad side of the crypto.
