Hey there! Everything is kind of proof of work in this regard after all, yes. I took a deep look into waves and first was enthusiastic when I saw BCH being a good way in. Though I got discouraged when I saw the withdrawal fees. I wonder why that is. It's a one way street. And I don't like one way streets if I can expect to sink what I sent.
Anyway, I'm looking forward to learning more every day as well.
