I like the name of the coin.
But what are the differences with Monero besides the fixed supply?
Monero is governed by a centralized team of devs, Iridium is built by the community and will adapt to whatever they wish it to be.
That's a good thing, every coin should have that aspect.
But how is this maintained?
It is maintained by a group of people that are interested in building this coin. It's not just the dev that has to do it all.
