When BTC dumps, all other coins also dump, it is worst thing because even if bitcoin dumps, then it should not effect the other cryptocurrency price value in BTC. i,e when BTC dumps the price value of altcoins is also drops while it should increase because btc downs. When people will realize it that it is not in their benefit?
I think when bitcoin dump why altcoin also dump, because when bitcoin dumps everyone will try to buy at the lowest price, so who hold altcoins sometimes follow the bitcoin trend. but when bitcoin is stable, altcoin will pump.
Yes, now the market situation is completely unpredictable because whenever Bitcoin dumps and Pump altcoin prices are kept decreasing and it is giving very good opportunity for the investors to grab the low valued altcoins. When again Bitcoin is becoming stable then the altcoins will start increasing their prices.
