We put a lot of thought about the price. We are against having it for free as this could lead to countless bloating blockchain transactions. What would you consider a fair low price per stamping? We chose this to start with because this seems in the same order as what other similar services have chosen. We would appreciate your view on this!
I am also against blockchain bloat, but how long do you think it will take for somebody to make a similar service and charge half or even less? Or maybe even provide it for free.
This service is very simple, so charging one euro per single hash is not only rather expensive, but also not competitive.
