Jonald keeps talking nonsense about segwit for some reason.
Wallets that aren't updated can still recieve regular transactions, also all relevant online wallets are segwit ready so this is a non issue.
But if they do not upgrade they cannot originate transactions that take advantage of any new capacity offered by the witness segregation, obviously. So this weakens the argument even further that its a meaningful increase.
Why not just increase the blocksize? That is what miners and most clear thinking users want.
Why do you choose to ignore obvious facts and spin everything?
