Bitcoins is a highly speculative bet in those terms, but the potential is staggering. Electronic money free from central control and low transactions fees, sent anonymously around the planet ignoring borders. Yes staggering. The genie is out the bottle, and growing by 1000's of % per year virtually. These bubbles are growing pains.
I agree on potential but that is not fundamentals to currency. This is called speculation and is high risk. Only people who are looking for quick profit or who are fools with their money would put a huge percentage of personal into something like that. Not everyone can afford to gamble with their life savings and investments.
A good example I use because my family works there and has made millions is Exxon. They are super conservative yet over the long run always profit and are paying dividends. We are dependent on their product and there is super low risks. Apple has a P/E around 9 now like Exxon but, their products change fast and are a huge risk. One small mis-step and they are screwed. Exxon can dump oil out and act horrible to the environment and yet they still make money. They are one of the tightest managed companies on earth and the largest. Bitcoin is almost the opposite end of the spectrum.
TL/DR - My original point is Bitcoin does lack fundamentals and with high risks expect big swings and price to drop.
Well I'm agreeing with you basically. I wouldn't put my life savings into it myself. Too risky. But I do think its worth having a stake in it because of the staggering huge potential. Only invest what you can afford to lose. If you invest in a couple of bitcoins, which one day are worth 10's of thousands of dollars you had nothing to lose, and everything to gain.
