Can you sell on both Rarible and OpenSea?

Can you tell me if it's possible to sell digital assets on both Rarible and OpenSea? As a cryptocurrency and finance expert, I understand that these two platforms are popular marketplaces for NFTs and other digital collectibles. But I'm curious if there are any limitations or advantages to selling on both platforms simultaneously. Do they offer different services or target different types of buyers? And what are the potential risks or benefits of using both platforms? I'd appreciate your insights on this matter.
