In historical BTC phases bear or bullish, its known that the USD price affects cryptocurrency. If USD aka DXY index is going up, we will see a downtrend in crypto as a whole. If DXY/USD is going down, we see crypto/altcoins start jumping 20% plus moves. So for a simple sum up, it is a very important indicator to use DXY in your crypto trading as historically, it has predicted the crypto market for 2-3 years to come. We are at very important crossroads at the moment with 200dEMA on bitcoin. This will decide what happens for the next 2-3 years in crypto altcoins nfts as a whole, whether we are in a somewhat bear cycle or bull cycle. Can't stress enough how important this is.
