What if Alt currencies don't disapear?! there are so many that have a real benefit to the Bit coin system.
A lower Block time is one big positive. plus if Bitcoin does break the 2000 or much higher it will need complimentary currencies so that we aren't all dealing in 0.0000001 to buy a Bigmac.
What benefit?
No , you can pay one sastoshi or one m
BTC for a Bigmac, there a problem?
Most people are not so clued up on millionth decimal points and if Bit coin is meant to be accepted socially then that is clearly an issue for the average joe.
also there are 100's of currencies in the FX markets what makes Bitcoin so special other than a 1st mover advantage?!
