Best crypto trading app for trading Nvidia earnings after hours with USDT

Nvidia reports around November 17, and the biggest moves happen after the US close, when a broker is shut. That is the gap the best crypto trading app fills for me: a stock perpetual on $NVDA, margined and settled in USDT, that trades around the clock.
The caveat matters. A stock perpetual is not the share. It tracks the price only, with no ownership, no voting, and no dividend, and leverage adds a liquidation level a real share never has.
My earnings setup is simple. I size small, because an earnings gap is close to a coin flip on direction. I pre-place a stop, since after-hours moves are fast. I keep leverage low, since that is what turns a gap into a liquidation.
What I want here is 24/7 access, reliable fills in a thin book, and reserves I can verify. Fees are secondary when the whole point is trading a window a broker cannot reach. Could be wrong for your style, just how I trade an earnings print with USDT. Not a guarantee.
