I mean, you have said it yourself, the public does not buy into Bitcoin even if it has good price history because it was involved in many scams. These past few months alone, many rug-pulls and scam coins have been exposed and brought into the mainstream and many people associate cryptocurrency with Bitcoin, they would have assumed that Bitcoin may also be another crypto scam.
Bitcoin really needs a mass-friendly PR strategy launch to distinguish itself from fraudsters. Spread awareness and information that can be easily understood even by the most computer-illiterate, maybe even publish real experiences of people who gained something out of Bitcoin. But that would be really difficult since Bitcoin is not really a company so it must really to its users to uphold its image.
Even if the intention is something good but on the other hand I would not really believe that it is useful because in my opinion with conditions like this convincing that we are different is tantamount to a defense as well as in this case by claiming that bitcoin is very much different even if it is true it will make it seem as if this is an excuse especially saying to people who are skeptical of bitcoin.
Skepticism like this will continue to exist and indeed will continue to exist but I think it doesn't matter for that, I personally feel that there is no need to convince skeptics that what we choose is right because indeed they have their own perspective and we have our own perspective. I'd rather continue to convince myself that this is a very worthy thing rather than telling others especially the skeptics. The risk is obviously there when we say this is a feasible thing such as when there are people who are interested it will focus on us because we are like inviting them, on the other hand for skeptics will always make this a defense reason even though what we say is true.
