I'll give a clue - it's something that has required significant monetary investment on my part (I'm talking 5 figures US$) before I can offer it to users. I'll reset the 24 hr limit for the users who posted before. You guys can guess again.
OK, my another guess:
You're going to implement CLAMS staking. Users will get some CLAMs per roll (or choose between BTC and CLAM), or users will earn shares (per roll/ref roll/wagered etc) in profit from CLAM staking.
ps I noticed that (for a while now) there are no ads on the site at all (other than the small ones from your own 'advertise' program). iirc after the adsense block, you used a different ad network, but now there's nothing. Is this permanent? How do you generate revenue?
