Back when the Internet became mainstream many questions arose about control & regulation.
Today we find YT & Google & Twatter & FB blocking people they don't agree with.
The question then becomes who & how will rules & regulations be applied to the crypto world.
Will they be new rules or old regulations applied to modern tech.
And then there is the globalisation issue. Some countries may 'ban' crypto, but with a VPN who knows where any user actually is.
Maybe VPN's will be banned? Maybe web pages that promote crypto will be banned.
But at the end of the day, stopping decentralised concepts is akin to trying to stop the dark web.
If regulators want to drive crypto underground in order for it to exist, the we can all find a VPN, TOR based browser and watch as they try & shut it all down. They being the baking cartel that pulls the levers & controls in our governments.
