I think that this is almost the same as stocks, I think people always overreact. On the other hand, it shows how small and concentrated bitcoin is. Whereas in all countries there are many banks, and if one bank collapses, the currency will not follow.

But one exchange sued (has yet to collapse), and currently bitcoin lost 5% in a fairly short amount of time. It's not normal. There may not be enough exchanges, so going down shouldn't have any effect on the value of the bitcoin.
