Peach Bitcoin ask their users to install their software in order to use their service, I don't feel safe and trust them. If their service is a web based, I would explore their site and compare the fee with the other sites.
One of biggest problem with DEX/P2P is lack of local currency. If you don't use USD or EUR, the option would be severally limited and sometimes with unfavorable exchange rate.
What do you think the solution for those people who want to use DEX/P2P but their country aren't accept USD or EUR? is there such digital bank that accept every currency and the fees is worth to use?
