I am trying it out. The only thing concerns me is that it requires 1000 SEMUX and vote to be able to mine.
I believe anyone who spends 1000 SEM to register as a delegate now will get the 1000 SEM returned to them when the mainnet launches sometime in 2018. Of course any delegate payments made after mainnet is live will be lost for good, so now is a good time to try it out.
There are 104 delegates now as I see in the Semux wallet, I thought dev said max would be 100 delegates. I would like to try that too before mainnet goes live.
There is not a limitation on delegates number. Even it can be 10.000. But verified delegates which can forge the blocks will be 100 when mainnet active, currently it is 64.
