We need easy to use, non subscription micro payments. I was hopeful Bitcoin would do this but sadly it was never adopted as a mainstream payment platform.
Bitcoin does not scale to micropayments. Lightning could probably help, but the next problem is that Bitcoin's value is way too volatile for broader acceptance (which, I realize, is to a certain extent a chicken-and-egg problem).
Unfortunately, the very design of Bitcoin doesn't lend itself towards micropayments, due to the limited block size requirements. Variations (BCH) and addons (Lightning) attempt to address this, but BTC itself suffers from design flaws that restrict this.
Stellar seems like a good platform for this. I'm investigating myself about implementing this, and it would be awesome.
