I agree that the number one issue is not scalability, but usability and adoption. However, the adoption will not happen until scalability is solved, or at least partially solved. As I think everyone who reads this channel agrees that cryptos aren't going away, but we don't know which one will get that adoption people dream about. I doubt it is going to be Bitcoin, simply because fundamentally it was not designed to scale to hundreds and thousands of transactions per second. Google was not the first search engine, Facebook was not the first social network, Linux was not the first Operating System, and we can find similar examples of massively popular technologies that were not pioneering at the time, but got massively popular. I’ve been learning about cryptos for only a few months, but as soon as I understood how bitcoin works I realized that although the idea of mining is cute it is not suitable for scalable solutions. Lightning network and the idea of off- chain transactions is simply a workaround to the scalability problem of the ancient technology Bitcoin. Yes, I call it ancient because ten years is an eternity for the internet technology. Lightning networks proposes off-chain transactions, but then why having the chain at all? Airplanes have wings, but they aren’t exactly like birds. Neural Networks have neurons, but they are not even close to the actual brain structure. We get inspired by nature, but we don’t imitate it exactly in technology. Bitcoin mining is a very close imitation of the gold mining, because it gets harder and harder with adoption and it has already reached the point of ridiculousness. I think cryptos that don’t require Proof-of-Work will win eventually, but we don’t know which one.
