I think right now every market runs according to US market.One reason is it is the largest market financially with companies registered globally and people invest in them from all around the world.Secondly US has the largest number of crypto traders and if there financial condition is not good than they will withdraw or sell their investment.
Not quite true! Every market is affected by the global economy! There's no particular national economy that can affect all of the markets even the U.S or China. Also, there's no statistic that proves the U.S has the largest number of crypto-traders not to mention a lot of traders in other countries registered as U.S citizens (fake info). Therefore, it's not accurate to say that all market depends on the U.S economy.
