Keep mining it, and holding-on... Only if you have the machines to spare. Launch to the exchanges was premature.
Yeah.. I'm keeping some hashpower on it.. went and picked up some BBQ and LKY, and a bit of LTC to pay the bills, then mined some orphans and did some maintainence while I waited for the difficulty drop and went all in again..
If the Dev doesn't publish his website, we'd be better off mining RYC... If he does and it's schmick, we got a winner.. If it's so-so, then we are in with a chance.. Whether the coin has support is critical to it's value.
There's a sea of new alts out there, not many have taken on and survived a faster coin targeting their niche, and have a website that accepts them in the first few days that wasn't produced by the Dev themselves.
Lets face it, SXC is just another clone, but it's value lies in that it is targeted at an industry that will need to move to a microtransactional business model as other entertainment industries (music and gaming) have done to survive, and it excels as a medium of exchange for that model.
I think it realistically has a better chance of succeeding in this than these other clones have of deposing BTC as the currency of choice.
