I completely understand that we do have different opinions about KuCoin, and I hope that everyone would respect that. In marketing terms, every exchange claimed that they are the best in the world due to this, and this, and that, etc.

Although I respect KuCoin, but I honestly disagree that they're the best for now. As of today, Binance is still the most popular exchange up to date (but I'm not saying that they're also the best). I consider all of the exchanges almost equal due to the features and functions quite almost the same.

Most centralised and decentralised exchanges have almost the same features with a little bit of their "unique" feature that may only give less impression to the traders. It's because what the traders are looking for nowadays is the big trading volume of these exchanges despite not assured of its security and safety. It is why I would rather store my assets in a cold wallet rather in exchanges.
