Bitcoin is hot, except when you compare it with ethereum or litecoin or bitcoin cash or some other digital currencies. And remember that the stock market and probably many 401(k)’s are up a paltry 20 percent. Still, bitcoin supporters have pointed to the rise of ethereum and litecoin, and now the hundreds of other digital rivals, as good news. But if other digital currencies are increasingly seen as rivals or even substitutes for bitcoin, then that 21 million cap becomes meaningless. But when it comes to being a store of value, bitcoin is increasingly being outsold.
