When we sell our productive time and energy or the fruit thereof, we naturally prefer to receive payment with a money that will maintain or increase its purchasing power over time, if such a thing is available.

When we spend our money to acquire someone else's productive time and energy or the fruit thereof, we naturally prefer to offload any money we have that loses purchasing power FIRST, before letting go of money that will maintain or increase its purchasing power.

A few things can be done to align the incentives of the seller and the buyer so that both prefer to transact in the stronger money.

1. The seller can make it more difficult to transact with them in the weaker money. This, however, may mean they lose out on too many sales.

2. The seller can charge more for what they sell when priced in the weaker money. This, too, may result in losing sales to competitors with lower prices.

3. The seller can offer more attractive pricing when denominated in the stronger money, while keeping the weak money prices competitive with the market.

4. The seller can exchange the weak money into the strong at their earliest convenience.

Eventually, no one will want the weak money anymore, and everyone will be transacting in the strong money, but that process takes quite a bit longer than just 15 years. #Bitcoin
