When beginners start learning technical analysis they start it from candle stick patterns. Its very basic form of analysis and may be follow at start of crypto but now they are no more reliable in market.
Doji is a buy, inverted hammer shooting star is a sell
I think this is now a scam.
Trading is not that simple if its simple like that everyone just come learn patterns in 2 or 3 days and start making money.
Look at the chart below from this candle mention in red traders started shorting $BTC and coins by this bearish candle pattern and market does not care about it.
So just keep it simple and follow the market structure and wait for more data for confirmation.
