I was wondering is there a reason why, when I am selling some coins on the exchange sometimes I get "Volume too Low". Some times even I get when the coin i am trying to sell more then even before Like last time I just sold some coins a total of 50 coins @ 0.00000500 had no issue. Same coin I go to sell on the exchange and this time i had 150 coins same price and I get "Volume too Low" sometimes if I wait a certain amount of time then it works. Is there a setting or something i need to know about?
