It appears crypto coins are adopting the razor blade strategy. I predict we will have a x22 algo in a month.
You guys can still mine Marucoins --- I did with my AMD 290x in the past. But now their difficulty is still very low, so it is still minable if you have AMD cards. Otherwise, wait for cc 1.1, maybe, :-). I checked the site that dev team is trying to redo the logo, etc. So seems it is still in active development now. The main argument here is that, when everyone goes for X11, and rumors about FPGA farms and x11 multipool hanging around the corner, the additional 2 algorithms will temporarily make them safer for GPU miners -- at least for short period of time.
When possible, mine coins that first implement some algorithm, they have higher chance of success in the future. That's the reason I mined some Maru, and not sell it yet. Same reason I still hold my HVC even the price crashed... (well, to confess, I also mined two days of MNR). Maybe DOGE is an exception here. I still love that community, and believe it may have some chance to take off... maybe even brighter future than LTC.
Given that, I personally would suggest mine some alternative coins with even temp 'additional' protection. Be it x13, x14, x15.... x100...
I haven't tried much Maru, I was late to the ninja cpu only launched and I barely tested the cgminer version.
Also X11 plus two other algos already coded for gpu, sound like dev had always his own gpu code... (took 2 or 3 days to phm to come up with his algo... ).
So I didn't really looked into it...
That's why I think later coins based on this algo have more chance to have some "success" as there won't be any suspicion and everybody will the code on launch. But clearly I don't think X13 or Xmore will have any real success (there isn't any innovation, just recycling...)
The development code for X11 looks good, I hope we won't have to wait christmas for the 880...
