Probit exchange was launched in 2018 but I started using the exchange in 2020. This exchange was established in Seychelles. The exchange according to my experience with them, has a good block chain technology which us used to aid fast transaction process, and also very safe, since it uses a two factor authentication, I think hackers can't come in to your account easily. The exchange trading environment is attractive to my taste, I traded mostly major coins I the exchange, but I left the exchange for a reason, which was the high fee rate. The customer service is very responsible and don't give slow replies to my messages.
