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!
Yes, that's true, For now if the price of BTC is down then the price of altcoin will go down. we have to be really careful in trading now, take a moment to buy some coins at a low price and sell them for a high price.
