We have been looking. It is difficult to find irreversible funding methods which are accessible to the general public. Those that do exist tend to have large barriers to entry.
Aren't bank deposits (Wells Fargo and BoA) one such choice?
Not particularly. They are time intensive and often new users need assistance. I was thinking more "retail". Like a moneypak but for Bitcoins. "Consumer proof". Buy, get a card. Nothing more complicated then that. If we don't do it, someone will eventually. It is the only thing which will bring transaction costs down to less than 1%.
