all of the above. i'm a bitcoiner, and i love to use it. if i could get friends to use it like venmo, that'd be great. i feel like those third party apps log too much information about us. unfortunately my friends are all hoarders or skeptics.

paying bills would be great too. i'm self-employed and the majority of my income is from day trading, denominated in BTC. it would cut out the middleman (exchanges, banks) and i could just pay directly. rent too.
