And what happens if assuming I refuse to give those info? Will be prevented from trading and my account get blocked or something! If there are no other stiff penalties aside from those, I think I will gladly refuse and find alternative, yeah, I guess this will make p2p more popular among crypto enthusiasts. What a calamity.

I don't think such regulations are fully enforced worldwide. I see if this is only in some countries. maybe the worst news if the regulation is true, many accounts will be temporarily banned before they complete KYC for transactions
Adoption is on the move government doesnt really like on what they are currently seeing on whats happening specially on a decentralized market which they cant able to control thats why it isnt surprising that they would really be making out some steps.
Good for those people who had lived on a country which are pro crypto and unlucky for those who do reside into those who do prohibit crypto.
Accept this fate because sooner or later we would see more strict regulatory laws which would really be connecting out on crypto market.
