Bitcoin take priority if your focus is on the ones it is used most often. The adoption of bitcoin in large companies today will probably spark more adoption in the future so that bitcoin will continue to be the most widely used crypto as a mean of payment. There are several altcoin that may be a payment alternative and are used by many in the future and I think it should be a low fee altcoin.

I am wondering why coindesk doesn't have BNB on their list.
