I do not think that. With the increase in the price of bit coins, why the price of alt coins decreases. In some cases, I noticed that the cost of alt coins decreases along with the decrease in the price of bit Coins. This is the reason why I seen advice from the experts. Thank you so much for your valuable opinion.
simple why the value of altcoins decreasing when bitcoin price growing is because a lot of people converting their altcoins to bitcoin my friend
so when the sellers is stronger than the buyers, of course the price will decreasing,,
by the way, you don't have to worry, because altcoins price will growing and follow the rising on bitcoin soon my friend
