Just because a faucet looks nice doesn't mean that it's profitable. Prime example would be your previous faucet. It looks great, and arguably is one of the best looking faucets in the industry. But is it successful? Profitable?
Current balance of 19 satoshi... Running a faucet takes a lot more than just building a pretty site. You have to start with a bankroll to be able to pay your users until your rewards and revenue from advertisers start kicking in.
I like the idea of your BluBTC brand, but if you're seeking donations, I would feel more confident in knowing what it's going to be, how many bitcoins you need in order to launch, and you keeping a transparent ledger of all donations that you have received. Otherwise, just because you've had a faucet previously doesn't give you the credibility you need to ask for donations.
Most people are going to associate you with being a scammer, even though that may not be your intentions. Why? Simply put, you're asking people for donations to launch a site that has a very vague description. You need to indicate what your target goal is, what you plan on using the money for, and provide a timeline so that we can keep you accountable for meeting those milestones based on our donations.
Either way, no one is going to donate to you... If you are asking for investments, it's one thing, but donations? Good luck mate...
Best of luck to you on this venture, and I look forward to seeing what you put together, but just be aware that just because you have a pretty faucet/app doesn't make you profitable!
