It seems interesting but how your going to measure the revenue from chat box only, in the first place? Also which charity will be the chosen one? What will be the assurance on app download page, that the links don't contain any type of virus or such things, in order for users security? A good advise that I would like to give, make a good rewards percentage for each of the rewards so it would be fair, unlike most out there, give almost 80 to 90% to the lowest reward and only 1 to 2% for their highest rewards. Also if you could implement a daily bonus, like in cases wherein the more they use your faucets every single day, the more percentage increase they would get upon claiming each time (there's one faucet doing this and is very popular).
That is easy to figure out, the revenue part.
Each advertising platform i am using contain special ad spot number that could tell me the exact revenue generated from certain banner ads.
The charity i have decided will be 'BitHope dot org'
Also i will try my best to make it a safe faucet for users.
I am still confused about the bitcoin dispense amount.
If i give too much that would be a loos for me and if i decide to give too low that again will be a big loss.
What do u think. an ideal payout should be?
