There are a few places where you can promote an NFT collection. You can start by promoting it on your website or social media channels(social media with more than 300k nft community audience ), and then reach out to other collectors who may be interested in purchasing your items. Additionally, you could hold a collector’s event to introduce the community to your collection and possibly sell some of your pieces. And finally, you could participate in online auctions or blockchain-based marketplaces to increase sales volume and bring in new customers.
Whatever route you decide to take, make sure that you put together a well-planned marketing strategy that targets both potential buyers and existing collectors. It is also important to keep up with current trends so that your collection looks fresh and modern when displayed publically.
