It will not be possible. bitcoin will return value 20k, but it takes time to restore confidence from investors. If it's a long-term investment, it's going to be easier, but with many investors seeing the bitcoin value as a whole, they are already hurt by the psychology and the big swings. wait and be patient ... bitcoin will be safe in the long run.
It will really take some time before investors could go back to the ecosystem. Not with all the regulations and the FUD and government banning. We need something concrete that will restore their confidence and says that bitcoin is still a good investment. Its really hard to imagine going from $19K to $6K but who knows, maybe next month we will hear something good that will change the attitude of our investors and suddenly pour their cash on the market.
Not everything is possible as there are somethings that are not actually realistic. No one should deceive themselves as this can only happen in a case where the trading volume is probably just $100.
We are talking about a huge capitalization here and even though it may not be that huge compared to when institutions want to kick, but obviously institutions always look forward to buying at dips and not just buying everything at once all the way squashing the sell walls. Moreover, market will always have a way of playing out and that includes several moves to try to break resistance or hold at a particular support.
