It has previously been explained very simply. People continue to fail to make the distinction between "money" and "assets". Money was intended to be a medium of exchange, a way to facilitate current day transactions, not a way to "store value". As long as the bitcoin has wild swings in its "value", it's not going to be much used as "money" or currency but will be traded as a commodity/asset just as people buy and sell wheat and wheat futures. Just because some people (drug cartels) use it as money because the value of anonymous large sums of money outweighs the risk of losing their shirt does not mean it's ever going to become "real money" for the masses. Even for the drug cartels, there remains a need at some point to turn the bitcoins back into actual "stuff" either directly or by exchanging it for "dollars". As with people, money should be judged by "what it does", not by what people "say it does". Right now bitcoin isn't currency and it isn't money, it's just an asset people are speculating on. Most likely it will go the way of similar schemes of the past, those who got in early will make a killing, the vast majority will lose their shirts. Why is this hard to understand?
