as much as I think I really could sell stuff as #cryptoart (and I really need some influx of non libre money now) , I just can't support the idea of all the energy (aka pollution) cost of those transactions made with "proof of work" blockchains ... :
for any transaction, Ethereum is using more than 30KW/h, so the same as I would use to cut ~10-15 1.25x2.5m wood boards with my CNC to make like 30 chairs or 6-8m of wall shelves
that amount of energy consumed _just_ to pay for the artwork is 🤮
