In my eyes a 5 digit number is just not gonna happen its way too much for the bitcoin and it cannot even simply rise to the 1k these days.
Maybe in about 10 years this is possible and even than its the question if it can.
5 digits will not happen in the next two years. But with the help of more adoptions and devleopments, it could happen in 5 to 10 years.
More adoptions and developments will just lead for an increase of bitcoin usage as a currency.
If that is the case, bitcoin price will not that go for a surge even for many years as coins will now be on a regular circulation in the world of currency.
