i made a point some time ago that if Bitcoin were to become a global reserve currency, much like gold, due to maintaining the 1MB block size, all Bitcoin 2.0 projects trying to ride the MC would be eliminated due to high tx costs. in that case, the blockchain would only be applicable to Bitcoin as Money:
Bitcoin
can't be money with a capped transaction rate.
Gold only maintains purchasing power due to being subsidized by central banks - there's no such thing as intrinsic value for a currency.
If those transaction rate limits are hit and the situation isn't fixed, then
Bitcoin will disappear.
I think Gavin has been working on a solution, where block limit grows over time, using the testnet. Which got me thinking--the fact that we have a testnet is pretty cool in itself--if only central banks had one to test interest rate adjustments!
