Why there's a need for you to involve chesscoin in your network when you already had a chesscash? Hmmmm because of the value of chesscoin?
Involve chesscoin in your network? You mean like as a currency or just in general? I involve BTC and USD in my network as currency since they are currencies. Chesscoin is also a currency.
If like me you setup a chess social network for chess fans globally to engage and exchange value then a currency created for the chess community holds at least a passing interest.
Interestingly I don't actually need chesscoin to run transactions on my site, it is more of an index for what I see as the chess economy and one side of a forex pair for those who wish to trade it, or HODL.
