Just a correction, these all are p2p exchanges but some of them require KYC like p2p platforms like Paxful and Noones have mandatory KYC.
Paxful and Noones are both the same exchanges if I am not wrong as Noones was started when Paxful was supposedly getting closed. I was not aware that they require KYC as I was under the impression that the do not ask for KYC till a certain amount.
Not same exchange but Noones is from the co-founder of Paxful and it came into existence when Paxful stopped their operation earlier this year but after a couple of months the Paxful came into action again.
You are at the wrong impression, in Noones it is mandatory to get verified even to deposit any crypto.
In Paxful you will get 10K euros limit if you verify ID and liveness test and if you need unlimited limit then you have to go through further like address verification and so on.
