How many people actually use BTC as money on a regular basis here?
Most people seem to treat it like an asset, hoarding and holding hoping for the moon.
I just recently put 0.5 on my cellphone mycellium app wallet, that was a big deal for me to commit to having a hot cellphone wallet. There's only one restaurant I can find here in San Diego that accepts bitcoin so I haven't had a chance to use it. I'm waiting for that day I'm at one of my regular places and I see a BTC sign so I can whip out my phone and use it
actually smartphone have more privacy than a desktop, if you know how to use it, and use awifi connection, with bitcoin they can essentially track your position, not who was sending that particular transaction, so if you have a phone you can just move away and your are done, repeat after each trasaction, i mean there isn't really the ip problem
paying in a restaurant should not be an issue regardless, if they don't emit invoice
using gold instead isn't anonymous at all, not even practical...
