Is there a GPU miner, or is it all wallet/CPU based? Also, I tried checking out the mining pools, but several were down, or didn't show the coin listed. Could you share a little more info? Danke!
You can mine on www.hashpool.co.za - pool is up and running and there is miners currently mining there.
Please see getting started page for ports and settings. http://hashpool.co.za/getting_started
Yes you could mine gpu / cpu but not recommended for solo mining - better to mine in a pool.
All these pools are live and miners currently mining Platinum Core on these pools
