users like instant payment better, having to sign up again and again to claim to same microwallet is tiresome.

but then again you get a lot more bots with instant payments.

Maybe u can create autofaucet script with login page having antibot links with time expiration and multiple shortlinks

U can give it a boost by adding offerwalls or a hourly faucet.

adding dice game would be great if u can integrate it with coinpayments API for deposits and withdrawals to faucethub.

A sidebar chatbox where users can spend time reducing bounce rate for site.

A mining function included connected to webminepool would also retain users for longer period.

To prevent bots maths captcha or some other captcha can be created like Allcoins.pw

Script can have a PTC function where users can pay to advertise their links too

I have posted this idea here and i am sad i am not a developer lol haaha
