Just curious - what is the deal with SIS coin? Are there any pools for mining, or exchanges where you can trade it?
As I understand it, when you mine SIS you also scavenge fees in other currencies - what currencies can be scavenged; I assume BRK, but are there others?
This is a very interesting and unique coin ecosystem. I am trying to learn all about it while I wait the 2 weeks for my BRX to stake

There is no mining pools at the moment i don't think , It requires some extra effort to get a pool going , different stratum or something . James will likely be making a pool in the future but since release his focus has been more on the coin than the mining pool, either he will get round to making the pool in the near future or i think there is someone else in the slack that has mentioned they might be sorting one out.
the main ones you can scavenge are BRK and BRX .
