Certainly an historic day for Bitcoin...
the only question is, "Who are the fools?"
Is it the buyers or the sellers?
Time will tell. Perhaps, it may take 3 to 5 years to know that answer. Any thoughts about when we'll know?
I would say 3 to 5 months... not years...
At least, we'll know if it was a bubble! However, the few last time it crashed, like in 2011, practically nobody knew of Bitcoins. Now it's much more mainstream, with many more "serious" investors.
