I have yet to see a convincing model (with numbers) of the bitcoin economy in the bright future; much less how we can get from here to there without being steamrolled along the way by banks, governments, and other competitors like Apple and PayPal. (I read somewhere that PayPal is already blocking any payment related to bitcoin.)
Having trouble believing you're who you say you are yet don't remember how the internet grew, or more importantly what it grew from? It didn't just spring to life as we know it today. Your trouble understanding how Bitcoin could (not necessarily will) survive all this shows you still need to do research into how/why it works. It may work better with "permission" from government, banks, but it doesn't
need permission.
The fast increase in value, for example, seems to have attracted a lot of undesriable players (greedy speculators, shady investors, incompetent businessmen, scammers...) which are already harming the project's image.
Again, a professor of computer science and you're not aware of how technology grows? Fledgling technologies are rife with just the type of participants you mention above. Don't forget drugs, porn and pedophiles while you're trying to besmirch crypto. By the way, it weren't for those awful greedy speculators Bitcoin wouldn't be worth anything.
Dang man, have you done zero research? This has all been covered. I would expect more from a teacher, which is why I believe you're here to spread bear FUD under the guise of "academic purposes." Again, I'm sorry your purchase at $1200 didn't pan out in a few months as you expected. Just hold tight. It'll rise again.
