It seesms like Bitcoin has formed a double bottom and could possibly be on the way to complete a W candlesticks pattern.
The upper long shadow + Bullish Engulfing is a strong pair of candlesticks and when placed at the end of a down trend it can only mean that the way is up.
In this case this 2 candlesticks are found just above the critical support level of 20k.
What's your opinion?
