Could you please elaborate on whether US-based individuals are permitted to utilize the services provided by KuCoin? Is there any specific regulatory framework or restriction that might prevent them from accessing or engaging with the platform? Additionally, are there any known workarounds or alternative methods that US users could explore to gain access, if direct usage is not permitted? It would be helpful to have a clear understanding of the current status and any potential obstacles faced by US citizens in utilizing KuCoin.
