Do I lose my apecoin if I sell my ape?

Hello there! You can own ApeCoin without owning a BAYC/MAYC.
ApeCoin in your wallet will not be removed if you sell an BAYC/MAYC NFT.

There are benefits to keeping your Bored or Mutant Ape. Recently we’ve had 2 staking proposals pass that will allow your Ape NFT to act as a key to ApeCoin staking pools. Holding these NFT has advantages!

I hope this answers your question. You can keep your ApeCoin and sell your BAYC/MAYC NFTs but there are opportunities through staking that require owning the NFTs. Its worth taking into consideration.
