Kucoin exchange is one of the biggest exchange in cryto community. I find the exchange very interesting because of it features. Starting from it registration, you don't need to submit any sensitive documents to register on the platform. Though if you want to make use of debit card or credit card you need to do your KYM. This exchange has high liquidity which makes it more convenient. It is one of the secure exchange platform in the world. It is a secure platform, it has two factor authentication. I never had an issue on the platform but it has life chat platform and email can also be sent to notify them for any issues or help. I love holding KCN the native coin of the exchange because of the added advantage such as dividend and discount trading fee. Although the platform is not regulated by any licence body but In my opinion that is not big issue because it really common in some platform. I highly recommend the exchange.
