Hi @bitwhizz and welcome. The total supply is 1,295,298 Sling coins at 3,300 sats (Bittrex) or ~$28,000.  It was half that yesterday and usually is between $10,000 and $20,000 total market cap.

I don't expect the market cap to rise much until I have finished developing a stable code base (we are getting closer) that we can use to swap our chain.  Please let us know if you have questions.
