Possible Disaster Scenario On BTC

When bitcoin price fell about 20% i checked the stoch rsi values on monthly structure,then i realize,there could be same price plunge scenario like 2019-2020 season,after i wanted to use same pattern like 2019,it showed me that the btc prices "could" go to 20.000$ line until 2022 if it can't break blue line on a monthly view,it is just an opinion.
