You can’t buy Titan on Coinbase. At least, not yet.
Titan is a new cryptocurrency that was created to provide a more secure and efficient way to store and transfer value. Unlike other cryptocurrencies, Titan is designed to be “airdropped” to people who hold other cryptocurrencies, such as Bitcoin or Ethereum.
Coinbase is one of the most popular cryptocurrency exchanges, but it doesn’t currently support Titan. That could change in the future, but for now, you’ll need to use a different exchange if you want to buy Titan.
