What's your take on Voskuil's view of multicoin scaling (I.e. BTC1 + BTC2 + BTC3, etc.)? I think it's entirely valid, I just don't know of it ever becomes neccesary (fees stay sufficiently low where everything stays on o.g. BTC)
Discussion
I think thats technically valid.
Another interesting insight is that increasing block validation time is scaling too.
