I've been using this Xapo wallet for last few days and I'm impressed. Would this not be a solution for all faucets? I don't know what needs to be done to implement it to a faucet but I know it literally sends payment straight to the users Xapo wallet which eliminates the need for the user to reach minimum payout. I'm seen a few faucets with this service and they are pushing it hard so it must be a cost effective solution for them.
I tried that website once, couldn't load it in the browser I was using. I found out it worked in another browser, but I didn't want to do that everytime I used it. Then I tried to see how to transfer funds out of it, and it requires a cell phone number (not everyone has one), it requires your name, address, and social security number. Also I found this article, and someone said something about them protecting your money but only if you pay to keep it in the vault, but I'm not 100% sure on that part. I just know from my brief experiences looking at their website, I'd rather not use it. Just my initial impression of them.
I don't like Xapo, like you said, it requires your name, address, phone number, and social security number. Too much info. Also, there are a lot of complaints. I personally think faucet box is best, but I read this thread, and some people have opinions against faucetbox, so I won't promote it here, but I like faucetbox.
