Yes! No new rules per say.
But some countries have implemented some level of regulation in the crypto space.
issues with respect to consumer and investor protection, market integrity, tax evasion, money laundering and terrorist financing.
Yes I agree with this as some countries have started a close monitoring on exchange websites e.g Japan.
Like my friend said, it would be difficult for cryptocurrency to be a sovereign currency.
And personally, I feel the involvement of Government is a welcome development as it would provide a more safer means for investors.
But as we noticed, the prices of various coins are faring well at the moment but let's not set aside or ignore regulatory threats.
