I can't buy groceries with Bitcoin directly anywhere around me either so what is the difference? You act as if everyone is using and accepting Bitcoin when they're not. Most people still don't know or care about Bitcoin.

If you're holding some fiat right now (and I bet you are) then it is quite hilarious to nitpick about Moneros security.

There is a ~$3 billion bounty for you to break it's security. If it's so weak, then go get it! What are you waiting for? All for you!
