True, voting (and unvoting) witnesses can be done at any time.
As for that coin, I don't know it and it doesn't seem to have any real value (for me) i.e. what problems does it solve? Making easier for people to run software that does nothing more than others can do? I don't think it's enough.
Hi @gtg
I am still learning about masternodes, so I found them complicated to build and complicated to maintain. I guess I see the use cases for Gin and Apollon coins as creating nontechnical point and click masternode creation platforms for people much less talented then you. But I see your point that for the technologically savvy like you it performs a function you already can do easily and possibly find stimulation and enjoyment in the process, which is understandable.
Thanks
