I personally think this is a big bubble. THe price has grown to big to fast. I just dont think the marketplace outside the SR supports the current valuation.
Unfortunately some people are going to lose alot of money... its just a matter of when.
One thing people fail to see (but they will), is that the 'bubble' is going to pop soon, but the 'bubble' is fiat.
You need to step outside the box when coming to understand bitcoin and what is happening, forget about certain 'economic teachings' and think with a new, clearer mind. The marketplace outside SR very easily supports the value, the marketplace outside SR is THE reason it's reaching these values, and will continue.
If you honestly think the way you say, then sell all your bitcoins now before its too late!

Yes, some people are going to lose a lot of money, but it's not the people you think.
