Bitcoin has a problem that becomes ever more apparent with its growing popularity. I would say the problem starts with its name -- Bitcoin. When you first hear the name you think it's referring to some sort of coin. Then, as you learn about it, you might decide "Ok, it's not a coin. It's more like coin-of-the-realm -- some sort of money. Then, you start doing the math and you discover that Bitcoin, even at its present value is worth many thousands of times more than any coin you're familiar with. In fact, if Bitcoin continues as it's been going, might be worth several hundred times more than it is at today's rates. It has nothing whatsoever to do with a 'coin.'
What's the solution? Start thinking of Bitcoin as something larger; maybe a house or a factory building or something. When you think of buying a single Bitcoin, think of it as though you are buying something huge, and substantial. Then you can wrap your head around such things as trading .0001 Bitcoins. Otherwise, it's very difficult to think about equivalencies. What do you think?
