Yeah you're absolutely right, they think that uᴉoɔʇᴉq don't have bright future, it also means that uᴉoɔʇᴉq not profitable and disadvantages for them. These reasons is the most mainstream people do.
Yeah people hold negative mindsets towards uᴉoɔʇᴉq and that is the reason they prefer to stay away from it as they have a feeling that uᴉoɔʇᴉq will not survive in future.
They will think that but when they see in the street and look at a shop that accept uᴉoɔʇᴉq then they will change their mind and use uᴉoɔʇᴉq too.
That will take a long time where we can see shops accepting bitcoin but before that people should have basic knowledge of bitcoins then only they will feel to use it.
