Regulations or no regulations it makes no difference. If the government chooses to ban crypto currency across the world believe you me decentralized exchange would take up the challah to build up a well secured transaction platform where coins would be transacted with ease and we'll securedly. Technology is actually advancing and there is no problem under the sun humans can't tackle with Blockchain and Artificial intelligence
Yes decentralized exchanges has always been the saviour. But these people has been studying cryptocurrency for years now, what if it is possible that they have found a way to get around this?
Although I dont see the possibility yet, maybe because I dont know whether its going to work or not, (not good with the technical aspect of things here), but I have seen news of how they plan to make use of centralized exchanges in having more control and a better edge in the cryptocurrency system.
According to the news I saw once, it says that whenever centralized exchanges or a custodial wallet user makes a transaction to a non custodial wallet address, they would be required to put in information of the owner of that non custodial wallet address. Wouldnt that be a way for them to be revealing those making use of decentralized exchanges? I am not yet sure about this, but we would get to see if its true or not.
