Answer: It is true that not all bought NFTs on Gate Market are available for withdrawal. This is because the NFTs are subject to the individual policies of the marketplaces that they are bought from. Depending on the marketplace, there may be restrictions on withdrawing NFTs due to the associated fees, or there may be other limitations that prevent the withdrawal of certain NFTs. Additionally, some marketplaces may require users to complete KYC/AML procedures before allowing withdrawals. Therefore, it is important to check the policies of the marketplace before buying an NFT to ensure that it is available for withdrawal.
