And that is exchanges who are keeping coins/tokens hostile for a long period of time. When I deposit or withdrawal from an exchange often times it just keeps it in pending status. Now I'm waiting for an idex deposit, 4 hours passed. My worst case was a withdrawal at cryptopia which took 30 days.
Crypto is not ready to be adopted by the masses. Lots of suicides would be the result...
You need to use another exchange then, if your coins are being held for hours then what you should be doing is contacting the customer support of the exchange so thy can resolve it. You need to understand that all exchanges are not the same and yes, there will always be exchanges which are better than others so you need to use the better ones
