The current bitcoin transaction fee is about $7, so nobody is going to be using this for everyday transactions, making $30 not much of an incentive. It sounds like there will be the option of choosing to accept cash instead, so it will be interesting to see how many prefer $30 of real, spendable cash over $23 of virtual, difficult to spend tokens.

Edit: Perhaps I was a bit glib as using the lightning network will probably solve the transaction fee issue. This could become an partially isolated transactional network, with less common transactions into or out of the network, like some SMS-based transactional networks in other parts of the world. In those cases uptake was quick as it was so easy to use (you only needed an SMS enabled phone). I am truly curious about how this turns out.
