At least on Binance Futures such a candle was possible. It's called short squeeze and happens if bears have to close their short positions, often induced by a cascade of triggered stop losses. Do we have finished the accumulation this time and start a new sustainable uptrend? i don't think so. Daily closes above $43k and a retest of the accumulation range would be needed in my opinion. Still, having a $5k candle on spot could be a strong sign, that demand is back and we go higher from here.
