I keep hearing about bitcoins, crypto-coins etc. To me it just seems like a very well organized scam. To me, if I can't trade it to fill my car with gas, it's not real money.

One of Japan's largest cryptocurrency exchanges has revealed that it's lost nearly $400 million in a security breach. ... The hack appears to be roughly the same scale as the 2014 Mt Gox theft, in which thieves made off with $400 million in bitcoin, causing the Japanese coin exchange to file for bankruptcy.
