Or, we could wait around another 6 months for the mempool to become unmanageable, and let Unlimited hard fork the network, which could unleash total mayhem.
UASF to Segwit, then:
1) Schedule a minuscule block size increase HF.
2) Prepare Schnorr and signature aggregation.
3) LN, sidechains, et. al.
You sound like you know what you're talking about. But I don't believe a word of what you propose will happen.
Litecoin adopted Segwit and nobody cares. The dump continues as we speak. I'm glad to hear that a few LN transactions happened on the LTC blockchain. Although I see no reason why they couldn't have simply used the LTC chain, LOL.
