On this chart you could see a channel where USDT is following a "somewhat predictable pattern" of bull/bear oscillation growing into the bull USDT market (and bears on the CRYPTO). But reaching a limit on the channel top as a resistance. This will bounce a correction into a BEAR correction for USDT.D, that for cryptos will mean a BULL market.
I've added a curved channel to give some potential constrain to the index oscillation.
Actually I'm using the USDT dominance, among others, to detect the general risk mood of the crypto investors.
This chart alone is not a good indicator, but it can be combined really well with TOTAL2 and BTC.D for a better crypto market understanding.
Even if this not an attempt to forecast or recommend an investment, it allows to have an easy to read view of probable conditions.
Just sharing my personal charts for learning purposes only. This is not an investment recommendation.
