Many new people joined crypto at the last bull run. Many even invested when the price of bitcoin and altcoins were at the spike. Suddenly in january all prices fell and many people lost alot of money but some got really rich (those who cashed out).
I think that people start to gain trust in the market again and money (also new money) is starting to flood crypto again. Soon when Media starts to advertise for bitcoin again, I guess it will start after bitcoin passes the 10k again.
You all should keep in mind: What goes up really fast, goes down also really fast.

Peace.
