Personally I wouldn't pay $600 for something that someone paid $5 for in recent memory. It's like buying a stock during the peak of a bubble that's about to burst.
To an average guy that just heard about some online investment opportunity where you put in $500 now and you get $100 more in a few days is a dream come true.
Here's the pivotal point: there's now energy, momentum, and attention.
The best thing you can do is establish domain expertise and market understanding and make bitcoin work.
Or else it's going to be the next betamax. Shit, that was expensive too.
