I've used Xapo and FreeBitco.in. Xapo faucet is owned by Xapo wallet so your payments automatically end up in that wallet. Same applies to FreeBitco.in.
The reason I only use and represent FreeBitco.in now is because they're the only wallet offering interest on deposits - 4% for doing nothing!? My balance would otherwise be sitting in a Coinbase wallet, earning nothing.
If you need a link, my signature url is active.
Coinbase isn't affiliated with any faucet. The only online bitcoin wallets that are affiliated with faucets (that I'm aware of) are Xapo and FreeBitco.in.
So is it a bad approach to use Xapo with faucets? I would appreciate if you could answer that question, and you could also answer it in
this thread.
