You can just consider this as some sort of correction .. each correction is HEAVY because BTC has no actual value. The actual value of BTC is the value it has BEFORE the bubble. The real value of BTC is directly connect to usage of it - and that was more or less stable before the bubble - used in "dark places" as a good currency to exchange illegal goods. Doesn't sound good? Sorry, but that's what it is. And THOSE markets will find another currency which will work better than BTC does NOW - because BTC - with this volatility - is pretty useless for everyone and will keep everyone from using it in terms of payment or good exchange.
