so there no way to mine it now?

sure there is, the wallet itself has a built in miner. GUI wallet even has menu items for turning it on/off
anyone know that but with current net hash 24khash/s still possible to solo? There way to co-solo?
Yep, with a 100 h/s, you'll average about 2 blocks per day.
I think volume and trading on the exchanges is low because Yobit hasn't update yet - traders are waiting to see.
