The question is, should I use bitcoin lighting or create an erc20 token?
not everything is worth decentralizing. It's worth to use decentralized solution for life savings (that's what bitcoin is for) but if your website is based on earning micro rates for short tasks, why not do it the old way and when the "employee" collects the appropriate amount in his account (for example after finishing 10 tasks), he will be able to withdraw in the crypto of his choice, incurring transfer cost yourself?
