Should this occur and reject, will treat it as a "Blow-off Top", signaling capitulation dump and bottom on underlying crypto assets.
For now, I wouldn't long crypto assets, unless they show clear combinations of bullish factors (structure breakouts, bull news, increasing volume, etc).
@MG1986_, this is the chart for USDT dominance. Normally when USDT.D goes up, crypto assets lose value, as more and more traders scale down to USDT thus increasing it's market dominance.
