I currently waiting for PRE-ICO stage of MIRA https://bitcointalk.org/index.php?topic=2367768.0, it is a solid team behind project, and I learned a whitepaper, and I found how they want to solve existing problems, and for it's clear. They create a special box to store lots of crypto which you can download this and it become an off chain, completely anonymous and secure. The Mira tokens are called the solutions, it is going to be used as an internal currency for the Mira's blockchain (ethereum based) and for paying Mira's commissions.
