The biggest concern that I've heard, is that Lightning Network could become effectively centralized in the hands of whales that control the biggest hubs in which most transactions would occur.
That's the point, the decentralization must be centralized now? Another FUD that I wanna understand is the 2x segwit HF. Can it be some kind of corporate takeover? IF yes, how that's will occur?
For the time being, Segwit 2x did not reach the minimum support needed to be implemented. There's "35 in support, 9 ready, and 37 in opposition" according to
https://coin.dance/poliBut according to
https://blockchain.info/charts/ there's 85% of the Hashrate signalling for the New York Agreement over the last 200 blocks at this time. So if everything stays the same, would we have another altcoin on november 1, and the Bitcoin code stays the same with only segwit activated.
I think that for scalability in the medium term the activation of the HF to increase the block size will be necessary in any way. Unless solutions such as LN prove to be efficient, decentralized, and secure enough to make bitcoin technology process payments faster. What do you think is the best scalability solution for Bitcoin? How can Bitcoin reach VISA and Master Card capacity?
