Not giving up lol. Just adding to the idea list, who knows an entreprenuerial person might be able to make something out of this.
Was thinking of 2 industries where coil micropayments or tipbot can shine:
1) "Pay to view ads/surveys". I remember in my college days signing up for this. You get a couple of cents per item and accumulate till you can cash out without being done in by the fees.
2) Recycling. Some collectors pay cents for aluminum cans, bottles, paper, etc. Why not pay in XRP drops.
I'll keep updating as and when these things come to mind.
