DUMB QUESTION: If you order something online and pay with Btc (actually send it), and what you ordered never shows up, you've just been scammed, right? How do you deal with this Btc flaw? (in this way Btc is pretty much like cash - at least with a credit card you're sorta protected from scams - am I seeing this correctly?)
DUMB answer: if your government decided to eliminate two most popular cash denominations overnight and you were preparing that cash to pay for your daughter wedding, what you are going to do? stay in 1000 people line? Cry? whatever.
If you want serious answer-market will evolve just like it always does , probably mostly on feedback, but it IS YOUR money vs NOT REALLY your money. Get it?
