Testnet

To get tTAO to register your miner on testnet, head to Bittensor's Testnet Discord channel and request tTAO! You will need to provide your miner's coldkey.

Mainnet

You can purchase TAO from many exchanges, including Coin Marketcap and Changenow.io. Copy your wallet's coldkey and send TAO to the address! For now, registration cost is typically around 0.1 TAO. However, keep in mind that subnet registration is a variable cost, so be sure to factor this into your budget. You can check the current registration cost on TAO Stats.
