Markets go up and down but ideas never die
If you are looking at BTC purely as a money making venture than, ya things don't look that great in the short-term. But think: you can only ever make a really big profit when stuff is cheap. No one gets in at the top of a peak and makes a lot of cash. The cash is made by taking a risk when things are closer to the bottom...
Besides money, if you are looking at the big picture of BTC and how far it has come in a few years & on top of that, how well it has been weathering some very big storms, then there is nothing to be glum about at all. I'd say BTC is doing fantastic.
There was a bubble. It's popped. BTC is fine though. It's gonna keep rollin' along and getting stronger...
edit: I think the wildness of the last few weeks have made it easy to lose perspective. Look at BTC's price over the last year. We are at 75$ right now. I'd say this is really strong. Honestly. I would say sub $40 is a weak price for BTC right now, and $50 is reasonable, and $75+ is strong.
Bubble burst. Tons of money in and out like that. Most of it speculation. Still a great many of BTC holders have coins and held on and will continue to hold on for a long while yet...
