Okay, I see that the author of the script the same as in Claim BTC and clones. Ads is somewhat and only from coinad.com. It does not guarantee longer survival of the faucet. Payment method direct or Xapo ... wtf why Xapo when Xapo requires ID number which destroys the concept of crypto currency that users can be anonymous. Think about it because there are several microwallet service ePay.info, FaucetHub.io etc. Overall faucet has potential but a big disadvantage is that after a claim has no a clock that counts down than only when the page is refreshed.
hello buddy,
#first: am not owner claimbtc script,
am owner of orabtc.com and we planing to made faucet's scripts and btc payment api (paid and free versions ).
and bitcoinbow.com is the first site to test our quality.
#second: maybe the theme like claimbtc because we all use material css platform (something like bootstrap).
#third : we are support xapo and btc address not just xapo. xapo is Temporarily until we finish our payment api. (because xapo paying without fee).
finally we choice xapo because not take too much fee from users but if you want to tell us any advices we are here.
be know we are developers team and we planing to made something big than faucets.
oh how to register I don't use xapo. 
!!!
