It was once impossible to stream movies over the internet because modem technology was limited to 1200 bits per second.
Even band-aids like doubling capacity wouldn't help enough.
Technically. Impossible.
Technically. Impossible.
For the original bitcoin that is currently being priced at $13,000 it is indeed technically impossible to exceed 6 transactions per second. Sure you could make a new crypto protocol, but it's not "bitcoin".
If your argument is "any improvement to the current system" "isn't bitcoin" then that's a no true scotsman sort of argument and I don't think it holds much water.
