Coins have their own, native blockchain. HIVE and HBD has Hive.
Tokens are created on existing blockchain: see Hive-Engine tokens.
Another example:
ETH is a coin native to Ethereum blockchain but there are also ERC-20 tokens that run on Ethereum blockchain, such as USDT or DAI.
Ohhh I see. I totally forgot that's why they called "hive engine tokens! " Thanks! Appreciate your time 🤗❤️
