if I have it right the maximum number of transactions btc network can handle is 7 per sec. coffee purchase and walmart trip has to go offchain eventually.
I've seen the "coffee" argument before (and may have used it once before). What would be possible outcomes to overcome it?
Bitcoin specie, for one.
Gyft cards for another
Bitcoin Asset backed debit cards...
New code...
The market will resolve this, probably around the time that a few more coffee shops start accepting bitcoin.
I feel like I should be adding #bitcoinisinbeta to everything now.
Unrealistic expectations are overextending it and folks will be let down if this is not all done yesterday.
