I think I remember crunching the numbers sometime late last year on doing the SHA256 for Curecoin thing with my S5s vs running them on Bitcoin - and Bitcoin won by a narrow margin on profitability.
Much lower hashrate but also much lower reward rate and it pretty much balanced out.
I suspect this remains the case this year.
Up side, I *FINALLY* got a FLDC payment - don't get me started on how big a PITA this wallet is, and how little feedback it gives while it's transfering anything, but it eventually worked - and was a nice non-small bonus. What I DON'T get is the bs about "have to have at least .0005 BITCOIN to cover transaction fees" - especially when the bloody fee was LESS THAN 30% of that on what had to have been a rather large transaction. SOMEONE is definitely getting over on THAT bs.
Unfortunately I missed the spike - but it was still worthwhile, though I'm not sure it doubled my income by any means.
For the timeframe involved it was definitely more than I could earn in a year from EVGA's silly little reward program (do keep in mind I've been typically #8 on Team Curecoin as ranked by Points 24 hours since very shortly after I swapped my current rigs over from Ethereum - not many folks that can match or better my performance at this point, and after my move next week I intend to add more rigs).
Any idea if there's an exchange anywhere for that MAGICFDLC stuff, or is it just useless fluff?
