Here's a weekly chart of BTC USD I've been working on. The bottom blue trend line, it's held as long time support. The moving averages are 21, 50, 100, 200. The purple is the 200, and the red is 100. Those are the ones to focus on. I circled every time the 100 and 200 crossed the blue trend line. It could mean absolutely nothing, but it did call the start of the last bull market, the exact top of the last bull market when the purple crossed. If this ends up being a confirmed trend, the 200 crossed it right where it would seem a bull market started in Jan 2019. I circled the 100 crossing as reference, as it's crossing now. It's an interesting chart for long term bias.
