Price of btc is not important. Only important parts of btc are volume of trade, number of transactions and businesses accepting it as payment. I personally dont have BTC to profit from capital gain, there are better options for that, less risky. Why I decided so? If BTC will someday replace US dollar and other fiats, the value of BTC wont be measured in fiat anymore, because it will be replaced by BTC... When that happens all ''value'' from fiats will be converted in BTC, so you will end up with capital loss not profit. Thinking about how it will be worth a lot of money is just like... in which money, btc is new money remember?
