You are right , this is universal thing that I seen my life for bitcoin market that if the market is going down then we have lots of opportunities to make more and more money.
With the down in the price of bitcoin , the price of altcoins starts to get rise , so with the sudden dump in bitcoin we should buy altcoins and also we should buy bitcoin at cheap rate Because dump in price is a opportunity to buy them for small increase in price and make short time buy sell profit.
Well here currently dump in price is stable , so we should not wait long and buy today and we will make profit easily in 1 to 2 month and also we can see that bitcoin is that coin of cryptocurrency field that is always profitable to hold for long term .
