Honestly, I'm not familiar with stacking in your wallet, but this coin requires that you leave the wallet unlocked.
I'm not saying it's a scam, but damn is that a security concern. Why not have a secured address that holds collateral or something? I've seen other coins (especially dash-forked coins) do this a different way with masternodes. This is hella sussy, I have a hard time accepting it as secure or something that is OK.
