I am so glad to see that this topic has been repurposed, and that you, irynet, are still giving this thought.
One thing that will lead to (greed and certain) collapse of your site is when players overinvest. Let's say that you offer a decent (not amazing, but decent) ROI that is very realistic and doesn't reek of "Ponzi". Now let's say that 100 users all of a sudden invest in that plan. Would you be able to pay back the 100 people their ROI on a daily basis, given the overnight spike in upgrades? How about on a weekly basis? What about a monthly basis? Chances are, that you won't be able to. Sites that claim that they can pay back these high-investing members from the advertising revenue simply don't understand how ad revenue works. Just because I invest 1BTC to upgrade my plan their site doesn't make the ads I view worth anywhere near that... Or any different from a free user on their site... So how in God's name are they going to pay me back my investment based on "ad revenue" as they claim?
Overall, I would love to see an exclusive faucet/generator that only allows a certain amount of users. You can keep the buzz alive by offering chatboxes and maybe some basic forums or a shoutbox for non-members to see how the members are doing... And it's a great way to start an email marketing campaign. You can take email addresses of people that want to join but just don't have the slots available for.
Manage expectations from the very beginning, and explain that you truly will be sharing your ad revenue with the members of your site. A breakdown can be done something like this (don't use these, I'm just guesstimating):
Phase 0 (the beta, development and programming phase)
100 Free Accounts
5 Level 1 Upgraded Accounts
3 Level 2 Upgraded Accounts
1 Level 3 Upgraded Accounts
Phase 1 (while you balance out your ad revenue vs cost of operating the site; maybe 30-60 days)
5,000 Free Accounts
25 Level 1 Upgraded Accounts
10 Level 2 Upgraded Accounts
5 Level 3 Upgraded Accounts
Phase 2 (After you have a good average earning per visit/user of your site)
10,000 Free Accounts
35 Level 1 accounts
15 Level 2 accounts
10 Level 3 accounts
and so on.
You could also do a transparent advertising report off of your AdSense and whatever other network you use, that shows registered members exactly how much you are earning from ad revenue. And then you do somewhat of a split like this:
Ad Revenue Split
25% to admin
30% to free users
15% to Level 1
15% to Level 2
15% to Level 3
You should also have a faucet available for any member to use (but mandatory for free members to earn satoshi and unlock weekly ad splits), or credits/tokens worth satoshi, and the value of that credit/token fluctuates based on how much advertising revenue you are producing. At the end of every week, or on every Sunday (for example), you can convert the credits/tokens to a BTC value to the users' accounts. Introduce a stipulation as a free member that if a claim is not made within 72 hours, your account and its balance will be forfeited in order to make room for new signups. Once your account/BTC address has forfeited itself, you cannot join the site again until your position in the waitlist has been rotated through again, after allowing the next person in the waiting list to join the site in their place.
Free members MUST claim from the faucet every 72 hours in order to remain a member. This also takes care of the visits on site, and metrics needed to operate a profit from ad revenue. With 5,000 or 10,000 visitors averaging 5-10 hits per visit within every 72 hour window, that's some good hits, that will end up paying back the investments made by paid members.
The reason you'll only have limited paid members per phase is so that you won't become inundated with over-investments, will undoubtedly collapse the ecosystem of your site.
You can use an email marketing program to send members and non-members updates about availability about positions, and as a way to introduce them to new trustworthy faucets/hyip's/generators that you trust and want to refer using your ref link. You can also earn a shitload of money from referrals to other sites... For example, I had 650 referrals from Field of Bitcoins that generated me 0.1BTC per week until their payouts went to shit. Bonus Bitcoin paid me an average of 500k satoshi/day until the Googlegate happened. Referral commissions can be added to your ad revenue, and split amongst the users of your site.
I think this will create an exclusive club that will lead to amazing user retention and time-on-site, as well as create a demand for your brand, as it has limited availability. Of course, the automation on the site has to be amazing, as you don't want to be manually checking 5,000 accounts to see who's been inactive in the past 72 hours... But I think that this is a great concept.
Badge/Recognition/Awards System
Every Level 3 user will get a badge or some form of recognition wherever their name is displayed throughout your site.
Everly Level 2 user will also get a badge.
As will every Level 1 user.
Free users can have the option to earn specific badges, like most claims made within the last 24 hours. Or the last 72 hours. Or the top claimer of the week. Top claimer of the month, etc.
This will help in the chatbox or shoutbox, or any social aspect you introduce to the site. Remember, it's an exclusive site for members, so you should offer them a way to talk to each other. Maybe also have a section/chatbox separate for upgraded members vs. free members.
Introduce a way to advertise on the site internally for members to promote whatever they want. Take 1,000 satoshi from their account for a 2hr ad. 5,000 satoshi for a 12hr ad. 7,500 satoshi for a 24hr ad. And then make a couple featured user ad placements that ONLY upgraded members can utilize.
If you do utilize this concept, and decide develop and program this, I would love to partner with you on this. My expertise is graphic design, marketing, SEO and advertising, and together, we could probably put together a business plan that could take off and start a new revolution in the way that bitcoin investment sites operate...
