Coinbase is a popular crypto exchange that is preparing to jump into the NFT space as well. The waitlist for its NFT marketplace was announced in October and is still available for users. According to Coinbase, invites will be sent according to your rank that can be increased when someone signs up via your referral link.
Unfortunately, at the beginning, it will be only available in the US but it is still worth signing for. A release to other countries is planned as well.
