Micro transactions can even be used for streamed content providers. A hypothetical scenario would be to pay per second of viewing for instance. How many times have you rented a video online and started watching it and then decided that it was crap and then stopped watching it. >
The pay-per-use concept is exactly what micro payments was meant for and this is ideal for the Lightning Network.
That's a very interesting use case you're proposing right there, something that I didn't think of from the top of my head. The same concept can be applied for music streaming services like Spotify. Would be awesome to see companies like Netlfix and Spotify offer 'flex'-plans to their users based on micro payments in the near future. Not only will consumers get more value for money but I feel like it will attract a new audience to these services. Either way it's a win-win for both parties.
