Just found out about this project and glanced over it and it is very promising. I wanted try mining BIS but I am a CPU miner and based on network hashrate, it doesn't seem worth it. However I will try to buy some from Cryptopia and will set up the node.
You are right. CPU-days are over a long time ago. The coin is still low at the moment so buy them is a good option. Do not buy too many due to I will buy a few in 2 weeks =) Good Luck anyway
