USDT hearing just ended without surprise, or say the "air" Tether is still stable so far. While before the hearing, people might dump USDT out of fear. So it's a good opportunity to use Grid Trading for stable/stable pairs like PAX/UDST to make profit from the fluctuation. I created a USDT/HUSD grid trading bot 4 days ago and have made 0.17% realized profit, which means a 16.44% annualized return from it.

The risk is low and the gain is fair. Here's the screenshot of the strategy:
