We have 16 days give or take till it kicks in. The stake rate is 5%, but I believe that with this being POSv 2.0 there is code for it to split the 5% of the total money supply among those actively staking, if I am correct, that means that if 50% of the coins are actively staking then the effective rate for those coins would be 10%, this is a decent incentive to get the coins off the exchanges and actively staking. I looked through the code and I think I found the relevant chunk of data but I am not a code monkey, if someone who understands source better than I could look through it and confirm, that would be awesome.
