Wallet sync is problem exchange is problem pools are problem. I dont know why. This is good coin but having some problems and miners dont like this.
"I dont know why." - just look on explorer :
https://explorer.vsync.pw/nodessome users do not understand the meaning of "MANDATORY : UPDATE YOUR WALLET TO 1.0.0.1 [VSYNC]" - there are still nodes with client v.1.0.0.0
Most likely they calls those problems. Do not know what client version are in use on exchanges, hope the right one.
Why is so hard to upgrade the client..., why they do not pay attention for it... maybe couse are in dozen other alts and hard to keep them all updated.
glad to see finally nvidia cards owners can join to the Vsync mining party.
