It is worth a lot, trust me I'm a Nincompoopp (and yes it's taken) Seriously vanvinh, you can play this neat dictionary word three ways, all of them equal $$$$.
Firstly, and I think the best angel is the 'Stock' angel. The .io is perfect for this expression of terms, money comes In, money goes Out = .io
Secondly, Personal and/or Property Securities ie; the protection of self and/or possessions. Huge Industry, Huge.
The third way will cost you.
