Interesting strategy! I always thought of day trading the highs and lows but never noticed this pattern. It is strange though, that you can profit by buying and selling on a schedule, not even having to look at the price! I upvoted this post because it opened my mind and am now looking to new strategies & patterns like this one. And a side note on USDT: Though I do not have full confidence in USDT, I do use it for short periods of time.
