Sorry, I Turned Off My Bitcoin Faucet (Because Money)
Promote shady offers that accept traffic from less attractive countries and that generate good revenue (mostly because they rob people who use their service from their money).
Use different types of coins – I ran only a bitcoin faucet and it made it hard to keep up with the rising exchange rate. Other coins have “more room to grow” in a sense that you can keep their payout lower. For example, with bitcoin I reached a point where I’m paying users 8-10 satoshis per claim. There’s not a lot of margin to go any lower with the payout (since you can’t pay less than 1 satoshi).
