I would not get excited with the announcement and wait for the user experience to happen first. There had been many such false claims by other companies in past and they all proved to be futile. So, we can not say that this time also the exchange will live up to the expectations based on the declaration they have made.
Even, if we see based on the popularity of exchanges, there are many other better options like binance which have proved themselves to much secure and practical for crypto users.
If you are indeed waiting for users experience, you may have to wait till next year when halving begins. The reason is that even if users were to use this new features, it wouldn't make any difference between this and the old one because the workload is the same, the same users and the same coin, little to no stress. The only way you can determine all the features listed above is when the traders stressed the future exchange and that cannot happen now in bear market, we have to wait for bull run to test the scalability.
I would admit that this thread is supposed to be on exchanges board for proper discussion since kucoin itself is an exchange, i don't use the exchange but if the improvements aimed were fully implemented accordingly, then this is going to bring for more use of this exchange from the crypto communities, what the people want are improved services over time, and with these nee features, they are going to also record some recent changes as improvement towards the use of their exchange.
I'm of the suggestion that it should be move to trading discussion, as the discussion is more specific on the future trading but anyone the OP decide is fine.
Kucoin use to be every trader favorite because of altcoins they listed, big exchange like Binance and Okx don't give this opportunity to retail traders and small money bag but the mandatory verification sent lots of traders packing to another exchange. The good thing about the future is down is very difficult to see people complain about their downtime in futures. Binance literally had downtime many time when they launch their futures but kucoin hasn't for ones that I can remember.
I don't know why they updated this now, or probably they are getting ready for bull run, who knows if they are expecting twice number of users from the last bull run.
