How do you see the future of BTC and BCH?

I have to admit that the consequences of the two different system architectures are quite hard for me to predict.

Unfortunately, I see both rather pessimistically, and I hope I’m wrong.

With Bitcoin, I see the problem that because of the Lightning Network (Layer 2), the system is becoming centralized. At some point, so few people will be running their own nodes that security could become an issue. Even now, most people use exchanges instead of their own nodes. On top of that, mining is also centralized by large corporations.

With BCH, I see the problem that if mass adoption continues, it will become impossible to run your own node because it will require too much storage, which mean a centralisation as well.

What do you think? I would like to see a more optimistic perspective.
