Could you please clarify whether the cryptocurrency Harmony One is currently listed and available for trading on the Coinbase platform? I've been hearing a lot of buzz about Harmony One lately and am interested in potentially investing in it. However, before making any decisions, I'd like to ensure that it's readily accessible on a trusted exchange like Coinbase. Could you provide an update on its availability and perhaps some insights into the process of listing new cryptocurrencies on Coinbase? Thanks for your assistance in this matter.
