many people in crypto or in this world have not touched bitcoin, the high price and the rise and fall of the value of bitcoin makes many people afraid or hesitant to touch it, if the bitcoin price is stable then many people want to have bitcoin. not all of the bitcoin coins in crypto are owned by everyone.
It is not just a bitcoin high volatile prices makes people worry but many governments have restricted bitcoin trading and crypto has a pyramid scheme so people don't know about bitcoin are a bit worried to invest particularly when prices are high. But most of the people who visit this forum on a regular basis might be having some bitcoins in their wallet already. I too had bitcoins in my wallet before I first visit this forum.
if the bitcoin price is stable then many people want to have bitcoin.
If prices are stable then traders don't like because they can't make a money on a daily basis and many people also invested for quick profits compared to other investments so if prices become more stable then you may lose some investors.
