UpBit is a very good one because it has a huge amount of volume on a daily basis, the same for Binance, those are my favourite ones because they work very well and you can easily use them. I think that there are too many exchanges now.
This one Upbit sounds new to me. Thanks for giving a hint:)
Yes, agree. Now there are way too many exchanges, and unfortunately, the majority of them are not as cool and secure as huge ones like Binance, for instance.
