You're absolutely right. I look at coinmarketcap.com at this moment and I see that Paycoin, a blatant scam, is one of the top 10 cryptocurrencies with a higher market cap than Namecoin or Peercoin. People aren't interested in legitimacy or being picky about who they do business with. They want convenience and promises of riches and they'll give up security and common sense. So the major problem with crypto right now is that the majority of the market participants are incredibly stupid. We'll get what we deserve until we start demanding better.
Human nature is the same whichever little pocket it spreads into. You can have the greatest tech ever but collective dumbness and greed will quickly piss all over it.
That's why it has to moulded and shepherded by people with more of a clue than the majority. Most are not equipped to be their own bank and never will be.
