Sorry to break your myth but LocalBitcoin is not decentralized. You confuse because it's a P2P marketplace. Now ask to yourself the following questions? Who owns the servers, who take decisions? who can freeze your account and confiscate your bitcoins? who can vote? To all those questions you can reply, "at least not you"

Now in terms of security, since you think CEXs are safer than DEXs: How many CEXs got hacked and how many DEXs got?
CEXs are more vulnerable to hacking, especially since the majority lacks of fundamental securities


Nobody asked the definition of a decentralized exchange here.
