"Nearly 2.7 trillion won ($2.3 billion) have been lost to crimes involving cryptocurrency in the last two years, according to South Korean government data."
where do you see the improvements being made against crypto criminal activity. this can really hurt the price for traders/investors if conditions don't improve.
it is really hard for the governments to control the crypto criminal activities. in such an anonymous system, it is really not possible to follow what kind of transfers are going on. i hope they can find a way to manage with this.
It is hard for the government to control the criminal activities inside the crypto world because of the system in which the users IP addresses can be hidden from others and if the criminals use the cryptocurrency as a medium from their transactions, the government or even the police cannot track them. And this is one of the advantages of using cryptocurrency although the crypto team is still falls under the government but the government doesn't have authority to manipulate the crypto world.
i think there is no any record about ip adresses on blockchain. As you told there is no way to record or track any ip addres in common blockchains. I dunno maybe they develop an alternative blockchain with a tracebility. But the question is, will the users want such a thing? wont they prefer to stay anonymous?
