Blocksize would need to become 555 MB in size for bitcoin to scale to VISA levels. +80 GB blocksize, EVERY DAY. This is why we have segwit and 2nd layer, and why BCH is doomed to fail.

This is what "big blocks introduce centralization" mean. When we scale to VISA levels, blockchain would grow 29 TB/Year. Not even mentioning what kind of hardware (besides storage) will be needed to confirm all those transactions. BCH developers couldn't see 2 weeks into the future when they coded in EDA. No suprise they are failing to see couple years in. All miners want is $$$ from transactions, not eventual world domination of bitcoin. UASF was a great success, thank you all for making it happen! via /r/Bitcoin http://bit.ly/2gLREdR
