You already have special advantages over regular miners when you buy the boosts and upgrades

I considered doing awards on the member page which only unlock on depsosits, but I suppose that's not what you want.

There is the option to upgrade to Premium Miner, which gives you a couple of advantages over users who are not. The most important for your specific mine is probably the fact that you gain free referrals. I am considering new things for the Premium Miners, but coming up with new ideas is a tough job. I do however always listen to users if you guys have specific ideas.
I understand that you mean "users who deposit in general" and not necessarily buying Premium Miner. However, those users already have a huge advantage in upgrading their mine compared to users who have not deposited.
Well you actually hit the nail on the head with your unlocking awards after a deposit

I'm not greedy or anything, not at all, I just like to be rewarded for the efforts I make x'D
I'm currently saving until I got 0.05 btc (already at 0.03, I'm considering the 6 month premium upgrade), the btc however I got, are all from other site's from who I don't really care, however I do care about this site (has giving me the most fun so far). And in a way I want to feel praised for redirecting all my earnings to this site x'D
If you need any ideas for the premium miners, give me like a guideline (what would be acceptable and what would be over the top) and I might got some ideas for you

Would be amazing if the premium miner would get some extra options

Since for me the only real upside about the upgrade are the free referrals and depending on their activity even that could be a punch to the nose x'D
I don't care about the captcha (I would even do the video captcha as a premium member, it gives you more revenue so ... :O )
Ow hey x'D Why not add a wheel of fortune where you can gather credits and exchange them for rewards?
place a little captcha on the wheel of fortune to get some revenue, let the premium miner choose between redeeming his ticket(s) at different stages + one forced redeem on the wheel itself.
The more tickets you have the more gold you get each ticket?
I for a second had the idea to base the reward per ticket on the gold you're mining right now per minute, but I don't really think that would be such a good idea, need to think about that a bit more ^^
But hey, you got a start already if you like this idea

First off, let me say that I am very pleased you like the game. The more you guys like the game, the more I like working on it and want to make it better and better
And yes I could not agree more. Premium Miners definetely needs more options, but it's difficult coming up with interesting things. I am not playing the game myself, and do not know what types of features you would like to see in the game. I would love for you to come up with more suggestions like the one you already gave just now. I cannot give you any real guidelines for suggestion. Anything goes I suppose and I will consider each suggestion individually.
I kinda like your idea. Initially, I did not want to include any gambling in the site, but changed my mind when I enabled the Sketchy Investments.
Can you ellaborate a little more on how you feel things wheel of fortune should be working with the ticket system?
EDIT: Oh yes and I will see about adding an award for users who depositted. Currently, there's one for users who upgraded to Premium Miner. Might change it to users who depositted instead.
