Coinbit, an Exchange from Korea, has a good liquidity in the market even though its functions are limited in terms of bank deposit issues, since it only admits the currency of the country from.
Its range of cryptocurrencies and its design of the exchange impresses me, although I have not used the app, in the web version it is well adapted, and its registration does not present so many problems.
The security of the exchange is assured and if there is a problem there is a customer service almost instantly in addition to having online chat to verify, I like it in a certain way.
