IF MARKET GOES GREEN
If market goes green you will still be making profit from your bitcoin that you are holding.
IF MARKET GOES RED
You will be able to multiple your Bitcoin by using your usdt or Dai to buy back more Bitcoin. It's simple as that, erase greed and focus on making profit from RED and GREEN Market.
This is definitely a good strategy, provided that the market continues to go green or continues to go red:) But we never know that. We only try to predict market movements. That's trading. There is no single, always effective trading strategy. You need to be flexible and prepare for various scenarios. You must gain knowledge and experience. Don't be emotional and invest only as much as you can lose.
