You don't seem to get it. Bitcoin is real money. Why would anyone in their right mind "cash out" into a depreciating currency?
Is this sarcasm? I can't tell.
Bitcoin is not "real money". Bitcoin is a virtual commodity gone viral. If you aren't being sarcastic, then it is you that doesn't get it. People are buying this currency, waiting for the price to go up, and sell it to make a profit. I guarantee you this is why 90% of the people have gotten into this game. It has nothing to do with decentralization.
