Re: Last Time. In small words. Why 2MB impossible. Why Soft Fork. Why SegWit First..

this is the only one, pretty new still https://bitcointalk.org/index.php?topic=1883902.0, has segwit and it's a clone of bitcoin in everything with 20MB block

This is incorrect. There are 4 that already have activated it or are just about to activate it:
1) Groestlcoin: https://bitcointalk.org/index.php?topic=525926.0
2) Vertcoin (will activate in a few days due to pressure via UASF): https://bitcointalk.org/index.php?topic=404364.0
3) Litecoin: Activates in a few days too.
4) Digibyte: https://segwit.digiexplorer.info/
