Nice to hear

First of all, you need to make some  plan of development
I'm newbie in coins, but I think you need more major exchanges, some marketing promotion and some "best practice" from other coins.

I think before trying to find something special (it's hard to find and you can't forecast the result) need to make the coin most convinient for users.

I write this just try to help you, no need any bounty

PS. I don't think that bounty for mining now is a good idea, the difficulty is low and value is low too. Better to spend some coins for increasing value of coin in total.
But some bounties for loyal users - very good idea, you need to think about some bonus system
