I don't want to spoil the party, but can anybody answer me a question:
What actual use has Segwit for Vertcoin? I never heard that malleability is a problem for VTC, and full blocks aren't either.
Segwit isn't only for scalability, it fixes lots of other stuff. See response:
The nature of a "soft fork" means that there will not be two chains, unlike a hard fork. This is because non-upgraded wallets still understand and follow the newer, upgraded chain. In terms of security, any transaction malleability is a bad thing and SegWit fixes that. Futhermore, general improvements in the Bitcoin Core software make it far more resilient against DoS and eclipse attacks not to mention the massive increase in sync time. Re-basing from Bitcoin Core also allows us to more easily incorporate further improvements in the future. In terms of Lightning, it's true that we don't have a capacity issue (transactions fees are negligible), payment channels are a great innovation in themselves and allow things like cross-chain transactions.
