Is there a particularly reason why all Coins are dropping simultaneously this week? If you
look at the charts you will see a pattern
if the reason why so many altcoins go down simultaneously I do not know it, and quite unexpectedly that all this will happen as now, and there is a lot of panic going on right now, especially for new investors and new traders, they frantically sell off some of their coins, lose all the money they invest, it's really a mistake for those who have sold at a time when all prices are down.
