Fykus said:crypto currencies are all well and good for a world currency standard but whatd happen if some sort of event caused power outages world wide and all the data re: crypto currencies got lost?
You would have to not just turn off the power but also wipe all hard drives. If you wiped all hard drives, good luck getting access to your money in regular banks.
In fact, due to it's decentralised nature you are much less likely to lose your bitcoins than you are your regular bank money (which itself is a very unlikely occurence). Much more likely that the politicians will inflate or directly steal your bank money though. No way for them to get their hands on bitcoins fortunately...
