This is awesome. I knew I followed you for a reason!
So much of what you say is true, but if you don't mind, I'd like to add a few important points to consider:
#1:There's this idea that just a few coins will emerge as mainstream coins, but consider the fact that, upon becoming a user of a product/service that crypto holds, you're also instantly a shareholder and a holder of inherent stored value! This changes everything! That's why regulation is so difficult. How do you regulate something new that is traditionally 3 separate things?
I expect that a majority of the financial activity that we currently understand to be wall street will eventually transition to this rewarding market. It won't be rewarding to them in the long run, since they're not actually users, but they make their profits off of playing middle man professionally, and I expect they'll do that until all of the actual users are also owners by default, which is beyond their control.
#2: While I understand your point on advertisement location being a significant factor, it's important to also realize that these locations have had decades, if not centuries of time to integrate a variety of different social and economic customs. When a cryptocurrency manages to fit that niche, and compete with traditional business, the potential is frankly unknowable at this time.
#3: A youtuber I typically follow, Ivanontech, said this fantastically, and it makes sense to me. This craze has a lot in common with the .com bubble. There's this notion that anything that is crypto is untouchable and amazing! As you stated, there's so much shadiness and fast money scams out there. It's important to learn as much as you can about a cryptocurrency, and in my opion, actually try using a service that they have, before getting involved. Quick gains may come, but you'll be on edge always wondering, just like you said, when will the uninformed speculators bail?
