There's only one way-reduced taxes or a lot of bonuses which they will get.
How will there be a bonus when you use bitcoins? I don't see any increase in the amount of bitcoins that I receive everytime I do a transaction. Reduced taxes? Seller still have to pay the same amount of tax even when he started using bitcoins unless of course he did on purpose to avoid paying taxes by not submitting the right amount of income that he has.
I think there are a lot of different options-for me the way how that will happen is not a problem as long as there is desire for that to happen.
This is the "If you want it, there's got to be a way." argument which I really fail to understand. I want to blow up the whole multiverse including but not limited to the universe that we live in. Since I desire that, there's a thought that's going to pop up in my mind on how to do it? I hardly think so.
And since you've mentioned that there's "lots of different options", would you mind sharing even just one?
If we as a community really want more retailers to accept BTC then we have to propose our offers
This is the desperate approach. "Plz accept out BTC, we'll give you money." No one in the bitcoin world would want to pay more than he should just to use his bitcoins. The way I see it, the retailers will start accepting bitcoins when our population has started to blow up.
