I don't think it's causing confusion right now.
But it surely needs to be changed sometime tho.
And if the rumour about poloniex addition is true, then it HAS to change since Siacoin is traded there.
I remember them asking for what the community wanted. Sooo, I am good with the SCS suggestion. or maybe just "Chips" would work?
I already suggested Chips, I think that would be the best ticker. But IMO is HAS to have something to do with poker or atleast have a P in it.
