How do the top faucets do it? I have a script with payments to blockchain wallet directly, but fees are too high for single withdrawals. I want to know how the weekly payments are done. Willing to pay someone for a solution, or if they can change my script to payout directly and use a micro payment processor (Xapo, epay, faucethub etc.)
You need a programmer who can code for you your desired feature. Use micro wallet payment processor to avoid big fees for small payouts. Micro payment processor helps you to reduce your transaction cost. You can also use xapo script which has no fees if bitcoin is sent to another xapo users.
