Jl777 just published a couple assets, didn't cashed out at anytime and still is working on many projects.
He told me last night that his asset was removed from Polo due to lack of volume.
He also told me had to reorganize lately because some issues with Nxt and also because his GUI developers bailed on him, but he has some new ones now. He is rapidly proceeding on his backend work which he codes in C (and can port to browser with Emscripten).

He also implemented CoinSwap and an efficient bitcoind client. Now working on an online wallet and the other things I mentioned at the link above.
jl777 is a prolific C coder. And he is knowledgeable enough to understand what I am saying when I chat with him (and vice versa). Long ago I used to have difficulty communicating with him (it was all like gibberish), but now it is has improved and the conversation makes sense.
I can't vouch for the quality of his code. I haven't reviewed any of it. I suggested to him to hire a technical writer, because his past white papers were incomprehensible.
We discussed some of his design decisions and I gave him my opinions.
Edit: I have no idea if there is no volume bcz SuperNet investors don't wish to sell, or if because there are no buyers or both. I haven't spent any time on the Nxt or SuperNet discussion forums.
