I think regulations are necessary.
The anonymity of crypto currencies can be and is abused.
There is money laundering, tax evasion and scamming people for their money when they invest in fishy ICOs.
All of that I consider to be anti social.
If a government finds a way to prevent this and if that way does not end up in too much surveillance, I would support it.
If that is the reason then everything should be regulated, because everything can be abused.
Regulate cash money, internet, news, social media, etc.
I think it's not a question
if, but the question is
when they want to regulate.
So many signs that they want to regulate it.
It's just getting too big for something they can't control.
