I think bitcoin has been building for a breakout ever since the June 18th bottom. Alts have had their runs against btc in the 2 months since the lows, so bitcoin dominance has plunged unprecedently low for this point in the market cycle (down to peak bull market lows). Crypto twitter might be the most anti-btc I've ever seen it. There's now been a shake out in the last week that damaged moral pretty hard. The most likely targets are around 40K or 52K, with a slim chance of a new ATH.
