I've been following it for seven years now. Why would someone do that when every other cryptocurrency can just have way more throughput? Outside of the propaganda bubble of /r/bitcoin anyone who takes a practical look at it thinks it is ridiculous.

None of the math about having 700KB once every 3600 seconds works out. Any cryptocurrency that is actually going to be used needs way more throughput. No one would think this is a problem if the people that are trying to sell you a second layer weren't constantly curating /r/bitcoin to ban anyone who questions why throughput wouldn't be increased first.

The only way any "second layer" nonsense works is if you can stop people from questioning why it is needed in the first place.
