Bitcoin and USDT deposits feel similar at the cashier, but they behave very differently once you start playing. Bitcoin's price moves while you play, while USDT holds a fixed dollar value.

The difference matters most for bonuses. Bonus terms are expressed in dollar equivalents, so a Bitcoin price drop during a wagering window leaves you betting a larger share of your remaining balance to clear the same target.

On fees and speed, the network matters more than the coin. USDT on Tron or Solana is fast and cheap, while Bitcoin is slower and pricier but accepted everywhere.

The practical rule is simple: choose USDT for a fixed budget or bonus play, and BTC only if you are comfortable treating your session as a Bitcoin position as well as a gambling session.
