If BTC goes below 9K many coins will go down big time!
Be careful!
I am not sure about this because I think if btc goes down below 9K, actually, it's a good time for altcoin to going up unless they losing their power to go up. maybe there will be any down time for altcoin too in this situations but I hope if bitcoin down, the altcoin start to increase and then bitcoin will come back to the highest price. every possibility can be happening in the crypto and it is better to stay calm if there are a down time for every coins and don't panic when you see this.
There's no going up happen when bitcoins fall since looks like the price of each alts are attached with bitcoins since if you look at it even if there btc exchange value will increase still their usd value will drop. But let's not look for it as bad stance since eventhough there's a fall there will be surely a good pump coming so let's watch closely for the comeback thrend with the bitcoins and the market.
