Espers sits currently on 13 sats. So cheap.
We have a few systems in place, to enchance security on the chain. The goal is to create fully secure chain, and sidechains where new tokens can be created, like ETH style. We have more cool features coming too but the mainstream goal is that, sidechains where other tokens can be built and run from. If you want to know more about our current security features, here's a few whitepapers.

We have custom masternode system coming in eventually, not a copy from dash's system. Android wallet is coming this month, iOS wallet later sometime. We will have encrypted messaging on chain too.
