>Consumer protections are independent of the payment method
Lie. You can burn Bitcoin, accidentally or on purpose, and it's irreversible. With other electronic methods you can't, and with physical cash there are circumstances under which the money will be replaced.
>Also, the only "traditional method" cheaper than Bitcoin transfer is handing someone cash in person
Lie. Bitcoin has transaction fees, and many informal studies done (when done by non-Bitcoiners) show it can't compete with the evil Western Union, never mind a normal credit card for day to day transactions. The case studies where the work is shown, and you can check the numbers yourself. The kind you never see Bitcoiners producing when trying to prove their case.
>There doesn't seem to be any indication whatsoever of failure
Lie. Those who did adopt it are dropping it because it gets them no business, and it costs money to support. In fact, the typical story is, "Small business adopts Bitcoin, sees no business, drops Bitcoin, receives dozens or hundreds of threats from people who never actually bought anything".
It's also dead as a store of value - the market value has tanked so you can't make it look attractive to the "get rich quick for nothing" crowd without going back to the very beginning for a comparison point.
Then, of course, there's the fact that there isn't a market small enough in the world to be supported by Bitcoin transactions given how slow the network is.
The only fix for Bitcoin's problems involves trusted third parties as middlemen - something that's fundamentally against the core reason to use Bitcoin - and those middlemen always seem to be businesses based on defrauding Bitcoiners.
Seriously, don't you feel the slightest bit of guilt lying to get new suckers into the pyramid scheme to bail you out?
