Good marketing initiative, but I think that you should probably do stuff that are a bit more specific than leaderboard positions.
E.g., perhaps run contests with particular leverage/profits? $10 for whoever is able to hit the highest profit with 500x leverage etc.
Just my two cents to keep the engagement up.
I can do that too if users like that. Let me figure out the rewards and I'll update you here when it is up.
I do like that actually, not only all the users will only fight with anyone but they can choose which leverage race they will participate and if they are confident then they can participate on each leverage to win more but you can start with small rewards and increase it as people start playing and coming to 500xbit.com
