I'm sorry, but I don't want to handle crypto, so this will not be possible.
Steam takes too much money away, so if I would start now to sell it on steam, i would need to raise the price. Because the price is currently really low and after tax and paying the selling platform nearly nothing is left.
I will see, maybe when the software is more developed and I will increase the price anyway, if version 1.0 comes out, than I will also go to steam. But, currently not.
Sorry, I wished I could help you.
