And then the multipools will come back.. multipools can kill an altcoin.. ramp diff up and sell sell sell
It really looks that AUR coin developer(s) do not know what they are doing.
Difficulty adjustment do not work well with big profit switching pools. And very very soon it come more bad after big amount of 0.1 - 0.5 Thash ASIC's are running and scanning over Scrypt alt coins.
You need set coin to profit multipool's resistant. (as all scrypt altcoins need do)
Dr Kimoto Grawity Well (KGW) need set very aggressive and fast (fast rise and fall time) mode (some time ago it looks like it was fast rise slow falling mode). It need be as fast to both - positive and negative direction. To undrerstand this dynamics need that coin developer team do some home works. Just with rule: learn first theory and after then use it for practice.
This is one reason why I stop mining this coin.
KGW is active in 14 blocks from now, so if you support the AUR concept then keep going until KGW has a chance to function.
