I think Bitcoin have gain more popularity to the level that people no longer go into panic selling when any negative news about Bitcoin came up, people mostly sees it as a long time investment, that's why it's displaying less volatility.
Investors have more faith now in Bitcoin because it always fight back in value no matter how the price depreciate.
Well, more people realized that. But definitely not all of them. There are still a lot of people who want to enter the crypto world to become rich quickly, fail to do that, and abandon it forever or for a long time.
I think those kind of people who hope to get rich quickly by hoping and speculating on Bitcoin volatility will not ceased to exist, and it's not only Bitcoin, those kind of people will come and go and then comeback when the Bitcoin shows some movement. I am not saying they are bad, but I just prefer that bitcoin will be more stable with wider adoption as currency, because it's the initial purpose of Bitcoin.
