For example: Let's just say Walmart in a year or 2 from now elects to accept bitcoins because it has integrated the protocol into their POS systems, fixed all tax compliance issues. Let's also suppose that the core Bitcoin devs have implemented a clever way to increase transaction thoroughput capabilities of the network.
Do you think that the price won't spike even a little?
Short term I don't really see it happening. By now you can already buy everything you ever wanted using the Gyft system, so I am not really bullish on something increasing sharply when you can already get almost anything at this point. I suppose Walmart would make it easier by not going through Gyft, but I believe Gyft gives you a 3% bonus, so then Gyft would be more beneficial than Walmart accepting it no?
The transactional economy will be dominated by boutique high value applications until software improves dramatically. The next moonshot I foresee will be driven by opening new channels for fiat inflows driven by speculation and reserve applications.
It would be possible for banks to directly work to convert BTC or something like that with a much lower fee or no fee. I say this because of the IRS ruling, so maybe more banks and creditors will look at that. If that happens I still don't see a reason for it to have a moonshot though, because at this point why would you convert to buy something in BTC when you can get 5% off by buying it with a credit card that has no annual fee, no late payments. Credit cards also allow someone to take on more debt than they currently have, a model not support by BTC.
