Why did you decide to use the ticker 777?
I don't know if you will encounter any conflict with 777coin later on because they have been here for so long already.
https://bitcointalk.org/index.php?topic=238323.0Just think of the possible scenario in case they learned your existence here, so you know what to say to them.
Also, are you going to attach your gambling license later on?
I honestly had no idea they existed it seems they are named coin but it isnt a coin though?
In my head upon creation I was thinking Jackpot and the first thing that came to mind was hitting slots with 7 7 7 so I went with that as the ticker.
As for gambling licenses we aren't the house it is all PvP we also create all of our own games.
