This is already not true - if I interpret blockchain.info's statistics right, so far, we had four blocks with more than 1 MB (these need to include Segwit transactions), three of them mined today:
- block
481947 (1,032119 MB)
- block
482152 (1,00003 MB)
- block
482187 (1,00003 MB)
- block
482191 (1,00001 MB)
So things are moving slowly, but they
are moving.
Maybe segwit is not yet fully active? If only few have block sizes more than 1mb that means segwit isn't fully activated. I thought it really will solve slow transactions if it is fully activated and as I see it now, I think it really didn't solve the problem but it is too early to say it. To judge whether it is really activated or not, I will wait a month or so because full utilization of segwit might really take long.
