It's a reliable service. When you know there's no KYC it's another bonus reason to test out using small swaps. If ppl like the service they'll become regular users when they need swaps.
eXch simply adds normality in crypto space and help people use Bitcoin the way it was meant by Satoshi: in privacy and anonymously. We need more such services, in order for people to become aware of their existence and, slowly, leave behind centralized exchanges.
There is no need to give away your personal information while using crypto, since (1) it was not meant for that and (2) you can do what you need in full anonymity.
However, the fact that OP became more active on the forum, the fact that this exchange operates for many years already, the good reviews received from forum users -- all these will help eXch earn more popularity, earn more users and these users will also spread the word to others and so on. Things are moving and, after many years, they are moving on a good path. There is still hope that more and more users will start preserving their privacy and will take full control over their money.
