If BTC goes below 9K many coins will go down big time!
Be careful!
I heard a theory that the market will crash to about a 250-300 Billion market cap AGAIN and then we we will go up from there!
Bitcoin falls and rises, this also applies to alternative currencies. Too much communication between them. I think you noticed that any fluctuations in the bitcoin price negatively affect the price of alts. This has always been and always will be.
