Hello,
Unfortunately implementing a faucet microtransaction API might not work very well for this plugin. This is because the balance a user holds is shared between the faucet and other plugins.
The correct solution to this problem will eventually be provided by the Lightning network. I have not had the time to test and implement it.
A BTC faucet is somewhat of an edge case – most users use the faucet to distribute smaller coins, and these coins do not have the high fees that Bitcoin recently had, due to them having less scale.
As lightning becomes more prevalent, Bitcoin should be good both for store of value and fast, cheap transactions, so I will try to provide an implementation towards that.
kind regards
Alex
