$BTCUSD Critical Support ZoneBitcoin / US DollarCOINBASE:BTCUSDHeadsUp2021BTCUSD: the green box is the critical support zone. Closing below $101K would be bearish and may invite further probe into the support zone, and potentially breaking it. I'm watching this zone and the white trendline to see if it holds on a closing basis. Certainly a lot of selling going on. Need to see if there are enough buyers in this zone.
