Does anyone knows if there are BTC based accounts with btcc.com or I can use only USDT?
There is no BTC-based account on our platform. Since we are a futures exchange and most of our trading pairs are quoted and settled in USDT, we only offer USDT-based account. However, if you wish to trade coin-margined futures such as BTC/USD, XRP/USD, and ETH/USD, you can convert your USDT to BTC, XRP, and ETH on our platform.
