There must be demand in cryptocurrency for the start of bull market.
Now more and more people use cryptocurrency and demand in digital assets will increase in the future.
A lot of new tools with cryptocurrency appear and adoption of digital assets grow.
Also many people actively use digital assets for investment perposes.
This is very subjective in my opinion.
No one can tell if we are in the bear or bull market, because it also depends on your point of reference.
However, if you are following a specific coin, you will know which factors will give you hint on where it is heading.
Better focus on the coins you are holding rather than look for the general market.
