It is true that being a reference currency can be good for that currency as there will be more demand for that.
It's all in the OP, no need to parse newsletters...
"(BTCD) is the conversion coin between different currencies for SuperNET"...
Implies that it will play a similar role to XRP on the Ripple network.
Also, BTCD will stake 5% of SuperNET revenues, that's the Big One = low risk play on SuperNET...
If SuperNET revenue disappoints UNITY is overpriced... but BTCD can still win the anon coin sweepstakes regardless.
It seems that all resources are being poured into SuperNET, which is the best strategy...
The time to promote BTCD heavily will come... James has made it clear over and over that BTCD is central.
