You may now use Caldera as an automated middle man for OTC trades at 💱otc-trades in our Discord channel at
https://discord.gg/nKWxnXV - between BTC2 and BTC/ETH/USDT/BUSD etc. It is an easy to use Discord bot. They take 2.5% from each side as a commission. Same risks as with any smaller exchange, but trades are quick to land in your wallet and you don't need an account at any exchange to use it.
