I have been observing Nym since its inception, I personally feel they are doing a good work and they have very good intentions. They need -unsurprisingly- more time.
As for the cryptocurrency, I personally feel it's a good way for developers to monetize and organize payment structures in a decentralized way. The best intentions to establish a decentralized system are worth nothing in the end if you depend on a centralized payment processor such as a bank or big tech. Unfortunately they haven't yet released a paper to dig a bit deeper, but I am very much looking forward to it.
