You know you not going to get a lot of people doing this for 25 bits right? This only creates dust in your address, because you cannot
even withdraw it without losing it to miners fees. So the people doing this, are effectively doing it for free.
If you want to do this, and
have success with the effort, you should at least be able to cover the miners fees. Yes, Xapo is free, but getting it on-chain is not.
