The withdrawal and deposits have been affected since a long time on koinex. I like many other fellow indians have experienced it every now and then. The real reason behind it has now come out. Looks like its the government is still skeptical about the whole crypto currency thing. The earlier the people in charge in the government make up their mind and come up with a concrete strategy about taxes and overall crypto trading in the country the better. Because one thing is clear whatever the gvt thinks or says, crypto trading and crypto currency is here to stay for the long haul.
