I think there is a good chance that Bitcoin will exceed $ 20,000 in 2021. It has to do with inflation expectations, among other things. With the money presses running at full speed all over the world, many investors expect rising inflation in the coming years. Bitcoin has a controlled declining inflation and is therefore attractive as an inflation hedge, just like gold. In some currencies a new all-time high has already been set in recent days. For example, take a look at the Bitcoin price in Indian Rupee.
It's only a matter of time before we hit a USD all time high.
