How much $ or BTC will it cost de tokens?
The price will be fixed $ 0.01 to pay for our services.

In my opinion, a fixed price is the right move. It would be cool if you accepted BTC.
you buy their coin for BTC and pay for their services, it's very simple.
It is easier for them to accept payments in one currency than in several, if the de coin has a fixed price, it is even better than the market one.
