I used yobit to purchase argus, bought some coins and price increase in yobit few times (3x) and I wanted to sell the coins. I placed sell order with little bit reduced price, I waited about hour and coins havent been sold yet,so i leaved and went to sleep, today i wake up and saw that still my coins are not sold and argus price now decreased and even smaller before I purchased... so i am thinking, why coins wasnt sold and how fast coins are sold? can somebody explain ? or maybe its better to use other exchangers ,not yobit?
This have practically nothing to do with yobit and the situation can always be the same when you move to another exchange.
What actually happened was that your sell order was not filled before the price got crashed.
You can only complain when you discover that the coin is trading above your selling price and your order did not get filled which will never happen in any exchange.
