I am been observing the way many traders and investors are accumulating different projects in the market and we all have to be ready because this Bitcoin halving is going to make the price of many tokens to skyrocket and it is only the people that are holding that are going to make money from the market. Last bull run, I was not able to make some kind profits in the market because I was too busy in things that would not give me the kind of money cryptocurrency would ever give me. We don't need to be slack, we keep holding.
The price of bitcoin is going to change the price of other coins too and as you are describing that other altcoins will skyrocket too when bitcoin goes pump so yes it's true and it's negative impact also effect the price of other altcoins in opposite directions.
Today as the price of bitcoin is decreased so you can see easily that whole market has been turned into red because every coin is related with the price of bitcoin. Those who cannot take benefit from current Bull season will work more and will wait for another Bull season and bull season does not come with ease but four years are required for pumping the price of each and every coin.
