Sadly I can't win that 25btc because I can't be first to get 180 days online achivment 
Why can you not get it, and where are the list of achievments and prizes listed?
Because he wasn't the first one that signed up? (< DUH)
Are the beta-testers and mods having a signup date earlier than everyone?
Again, this is wrongly assuming the first to sign up reach all other achievements before somebody that might sign up today. Registration date might help, but it's just as much a variable as any of the other achievements.
Of course, but still I would like to know if beta-testers and mods have a little bit advantage in chasing the big 25btc jackpot.
Nope, ours accounts are made only like 1 hour before launch . So we don't get 1 day headstart 
.
I see. . My account is made couple hours late because dev had to go bathroom at supposed releasing time...
And I'm sure someone who made account at the start will make those other achivments in 180 days because that is very easy $15k for them.
And what? Mods got 1 hour head start
I didn't even know that yet. That is very unfair 
.
