No other coin has such an injustice as with VIVO against ordinary miners. Every time I try to mine, I see the same picture - more than half of the blocks go to a secret private pool and after a couple of hours of seeing how the blocks go past the altminer and dutch, then I switch the rig to another coins. Developers need to do something about this, it's very bad for VIVO.
I enjoyed mining Vivo a few months ago when it was still active in Novaexchange. Unfortunately, the hash rate went up so much that it was no longer profitable for me to mine it with my rig. It became apparent that I have to mine other more profitable coins and the buy Vivo from the proceeds.
