To everybody claiming this is tulip bulb mania, here's a question for you:
If Bitcoin is just a bubble and will become worthless soon, where IS the money going to go for a demand for a safe haven from another market crash? Whether Bitcoin is the answer or not, there IS a demand for an investment that's easy to move and is essentially immune from regulations, seizures, inflation, and uncertainty of the overall market.
We're going to have another crash like 2008, it's just a matter of when. Glass-Steagall is still repealed and we've done band-aid efforts at best that don't prevent a similar crash from occurring. When that occurs, Bitcoin's value will go even higher, since it will be relatively safe from whatever antics governments due to prop up failing businesses and the stock market in general. Now if Bitcoin crashes before then, what's taking it place? The DEMAND for what it does will still be there.
I do agree that Bitcoin seems to be failing as a currency, but as an investment medium, it's not obvious to me what's going to displace it.
Of course there's a demand for a way to move money around without interference from governments. The problem is, this won't always be the case. I don't think the money is going to disappear, but it will certainly plummet the price of bitcoin. Anyway, the fact that it was under $1000 a coin a year ago, and now almost 10x that, scares me a ton. I cashed out at $6000/coin only like a month ago. When has a rise in price this fast ever been a good sign?
