Thanks for this, your view is appreciated. But I don't totally agree with you as correlating NASDAQ and Bitcoin is not professional in my view. I've seen a lot of people mentioning this correlation, but they do not always happen. It's true that situations make them move in the same way at times, but check their charts, the curves are not always the same, so I will avoid using one to invest in the others.
That said, I like the idea of DCAing, but now, I will have almost my investment in bitcoin, and the trick is for me to locate the bottom and buy it, then move it to USDT when a bearish trend is established (for holding).
This is solely being done with the help of technical analysis, and it has been so productive for me since last year that I got fully involved in BTC.
