New CME gapChart made a new CME futures gap between 8765 and 8865. This gap will be closed either before the dump, or after the dump is over and price bounce above 8k. I'd prefer to see it untouched until BTC hit 8k, as this will be more bullish and promising. In case price first go up and then down, there will be less "reasons" to come back.
Bitmex/Binance has a little different numbers, but close. Zone from 8150 to 8300 represents strongest support for bullish bounce. 8000 obviously can be wicked within that move as well. If bullish bounce scenario won't happen, price may retrace further to 7555 - 7700 zone. That still leaves the big picture positive, while switching BTC into consolidation period that will take longer time to resume and build new uptrend.
