Thank you!
I like both OpenSea and NFTshowroom. OpenSea is still like eBay was back in the day, it was basically the only game in town even when there were still other games in town. You can sell some elsewhere, but you're more likely to sell more on OpenSea. It wont take long for the other platforms to catch up. Atomic (Wax) is doing very well and so are others. Hive is doing well in terms of some NFTs but mostly game assets at the moment, but with those massive amounts of new Splinterlands or other game accounts comes many new users in general who will be browsing NFTshowroom.
