He said that we all hope for mass adoption. Well imagine if there was somebody prominent in China, that advertised Bitcoin and whole nation would see this in TV. Imagine if we would get an influx of 10 million new users over a very short period of time, Bitcoin network would become paralyzed.
Killer app, monetary crisis, mass marketeer, successful remittance company, bull market kickoff....
Just to add to your example.
Well exactly this, there are many things that could happen and trigger even a much higher adoption, if not a mass adoption. We never know what tomorrow brings and I would rather be ready for this very possible increase, than caught off guard and have a Bitcoin network paralysed.
And also to add, can we all imagine, what kind of message would this paralysis send to all of the newcomers!
