@Dev
Why are you releasing this so soon? Either there is an old thread or idk what, normally people have coins ANN'ing them for a good week, Put you only made the ANN today and releasing it? Are you sure enough people will see this coin and be ready to mine & have support?
Best of luck, When you reply i will decide to invest into this or not.
I believe a pre announcment about a day in advance is the best amount of time to be concise and keep this as a hot topic without it lingering off. I'm sure enough people will see it. But remember their are always those that say ahh I knew about this coin I should have mined when the difficulty was low, that's just the way it is and if someone believes in a coin they will want to get in on it it's simple as that.
