I've got the point where as soon as someone on TV starts talking about Bitcoin, I roll my eyes, and just turn it off. They rarely have anything of substance to say. Usually, the same regurgitated crap that everyone else says.
You're right though, they have bias for speaking that way.
3. People do not need "expert" knowledge to invest in Bitcoin. You go to computer... navigate to a local Crypto exchange... open an account online and link the account to your Bank account. Then you wait for the price to drop and you buy some bitcoins.
So, while I do agree with most of your points. This is where I don't agree, while buying Bitcoin might seem easy from a user that has been doing it over several years. You present the idea to a person of the general public, and they wouldn't have a clue. I still have people around me asking whether you can buy real things with it...that's how misinformed the public are. That isn't of any fault of their own, the news has pushed this idea that Bitcoin is rather worthless, and limited, which at the beginning could have been somewhat true, though times have definitely changed.
Anyway, the reason I disagree with this somewhat is; basically as soon as you buy Bitcoin you're effectively your own bank. So, if you wish to hold a large amount of Bitcoin you do need to be security conscious, and hopefully have some knowledge about it. Now, this isn't common knowledge. Securing money is something we've relied on banks for years, and years. We don't need to have any knowledge to rely on these, since they do all the security work for you. Whereas, that isn't the case with Bitcoin. Obviously, users like you, and I might see the lack of a third party as beneficial, but not everyone will due to the lack of belief or knowledge they have.
Effectively, to be able to purchase Bitcoin, and secure it properly you need to learn about common security practices i.e strong passwords etc, isolation be it physical or virtual, and the drawbacks of that. Plus, social engineering prevention, securing credentials, and/or wallets physically.
There's a ton of work including learning the software that Bitcoin relies on i.e Bitcoin wallets. This is much more than just linking up your bank account, and buying some Bitcoin. That suggests that the person is leaving their Bitcoin on the exchange, which is definitely not recommended as we all know.
Fiat as become somewhat easy to use over the years, Bitcoin has a long way to come, and probably won't ever be as simple as fiat, due to the fact you cut out the third parties which do much of the work for you.
