This was taken on a smaller time Frame that means you are scalping. You must have added some indicators to guide your process. At this point it should probably be hitting the lower Bollinger band and signal a buy. Just s guess because I only use small time Frame after analysis using big time frame and then check for entry point on small time frame.
Don't always rely on Bollinger band to show a signal for buy or sell especially a small time frame as scalpers use. At such candle indicating bear, you also need to study other indicators , not only because the candle has gone towards the low of Bollinger band. A longer time frame is better than a short time.
I'd preferred to look into its 1-week or longer performance for more basis and we can also evaluate the possible trend to show. But, for the fact that the market remains highly volatile, I don't rely upon on candlestick this can be just a lie.
Trading is tricky and that we need to have focus and don't let our emotions control us. If we mistakenly buy Bitcoin at the wrong time (which is unpredictable) waiting is gonna be our solution, not selling for lose. We need to study the market first before deciding. I believe this is very important.
