If you think about it from a financial instrument perspective it is relatively new AND undervalued. The more people look into crypto the higher the market will go. Weirdly enough if you have bitcoin or have just recently gotten into bitcoin you are still in on the ground floor. Once bitcoin goes into the 6 digits usd its not coming back. All the people I know who have crypto are still trying to grow their stack. Add that with the untapped market who have yet to dive in and you have yourself one hell of a bull run.
I see different moods, there are even those who are selling everything now, because they sure that the price of bitcoin will still fall very much. But this is too high a risk, since you can be left without bitcoin, or buy it later but at a higher price than you sold it now. I am also hopeful that bitcoin price will break 100k in this bull run, so I am still buying. But it is also not clear how soon we will go to the new ATH, the bear market may be this time more protracted than it was before.
