I've only used bithumb for about six months and so far it's working so well for me. the best thing about bithumb comparing with other major crypto trading platform is the fee, it's much lesser here than the other. there are several cryptocurrencies from which you can trade the ones you need and also the process is updated quickly so that you can take advantage of the fluctuations in the market price. the interface is simple and attractive, I found it very easy to navigate through the site even with a lot of content in Korean present in it. the account dashboard and settings are also pretty good. you also have options to enable two-factor authentication to improve the security of your account.
