Seems pump-and-dump attempt.

More interesting thing is a 170K mmc wall at 3600...
I don't see the wall on Polo - maybe it's already gone.
When you say "wall", you mean that, at 3,600, 170K of MMC will be sold thus pushing down the price, correct?
Is it possible to have a "fake wall" if one does not own 170K of the MMC?
Somebody set sell order of 170K mmc at 0.00003600 BTC. Now it's 66K mmc at 0.0003700
And no, you can't set a "fake wall", because you have to hold the coins in your exchange wallet to trade them.
So when you say the 170 MMC sell wall is "interesting" it was "interesting" because...?
Forgive my naivety but I'm just trying to understand.
Understand what?
Is this the same coin that Freetrade developed some years a go?
Yes.
But some of this clever guys (I don't know who exactly), was able to modify original mmc code to make it impossible (now) mine mmc with GPU.
Delinquency did that and I still think it's brilliant. By the way, Memorycoin was originally designed to be GPU/ASIC resistant but it simply failed in that part.
GPUs along with botnets hit this coin badly and made it depreciated. Therefore, FreeTrade abandoned, Delinquency took over and designed the coin impossible to be mined by GPUs/ASICs.
As the coin supply is reduced dramatically couple of months ago (again based on original design), all the coins in the market should have high intrinsic value. In other words, you have a great chance to resurrect the coin now as the base is stable and you guys can make a difference and make it appreciated.
