when was the last time you "spent" bitcoin if ever? why aren't you doing that? and that simply is one of the biggest reasons why!
I spend bitcoin almost every day (last time was probably last week tho) - either to purchase something where bitcoin is accepted, currency trading or investing in some shitcoin. So I don't think I'm a part of the problem if anything I'm contributing to the fluidity of the ecosystem.
the volatility and the "hope for big profit" has made people only consider bitcoin as investment for the time being.
That's only logically because early adopters of the coin have made profits, whether they bought while it was cheap or mined when the difficulty was still considerably lower, and as a digital asset in the decentralized niche, it's proven to be quite the durable investment vehicle. And by the way, everything is volatile the only difference is the rate.
none of these have anything to do with regulations
I quite disagree here, we can correlate more frequent fluctuations in price dynamics with when jurisdictions began to spread their opinions about the digital ecosystem. Besides, with the tangible prospects of the derivative digital markets, regulatory infrastructures weigh in heavily. And truth be told, the moment the US says Bitcoin is legal, trust me, we'll achieve hard cap.
reason why a supermarket for example doesn't accept bitcoin as payment
Volatility may play a role in reserved positions of retail business adoption, but still, that's because they'd prefer to store their savings and profits in gold, bonds or some regulated stock because they are 'regulated.' Notwithstanding, the true culprit here is ignorance.
