Yacoin fails in many ways.
 First of all, it was released immediately and withount any announce - "1.5 days later" with technical premine - so, many of us just hadn't time to react.
 Initial difficulty is way to low, blockcreation speed is abnormal and all that cause unaffordable amount of stales and orphans.
 I insist that it should be relaunched with clear launch date announce (at least 12 hours in advance), initial difficulty should be adjusted.  

 If none of proposed actions will be done, it should be understood as one of the scamiest scamcoins.
