At end of the day,this is just people's opinions.Just because many people think that something will happen,that doesn't mean that it will happen.
The Bitcoin price will go thru new price crashes and new ATHs,this is completely normal for a volatile asset like BTC.
I don't think that people's expectations about Bitcoin vary sharply "according to regions".I think that they vary sharply based on demographics,not regions.Young and more tech savvy people are more optimistic about BTC,while the seniors are very skeptical or think that BTC is a scam.
