Unless you think that you can offer the same or better rate than any of the current campaign now than it is worth a try. Bear in mind that signature campaign wont be always succesfull.
Regarding the faucet thing, 5 clicks/hour? thats too many unless you make the picture big enough to hold of the faucet licker since there will be user with multiple account trying to gain some from it
Also, regarding discounts: you don't exactly "buy" clicks, you buy BTC balance, with which you can do clicks
Well it is almost the same with what my thoughts of it . 100 % deposit bonus is a good start for promotions but there should be atleast some wagered amount before it can be withdraw or else you are giving away free coins
Yes, maybe 5 clicks/hour are too much, probably 2/3 clicks per hour are fine. I will try to implement security precautions to avoid multiple accounts, but it obviously can't be 100% unbypassable. We will start working on it pretty soon, so expect to see the new updates in some days! We are always open to new ideas from the community.
