Right from the moment they ban their own local centralized exchange Wazir ex, India has been harsh many times to it's people and crypto regulations
I believe that India isn't in favor of any exchanges and they want all of the exchanges to strictly follow the rules and regulations of their government in order to operate in their country. I don't think that any of the exchange is going to work well in India and if such level of oppression of exchanges continue by the Indian government then that day isn't far when Indian investors will have to look for alternative ways to use those exchanges.
Yes and they have to move their coins from that exchange to another exchange which legit. In my country it is one of the best but recently I discovered that you can't withdraw if the bitcoin is below 0.00005 and if you mistakenly deposit 0.00004 to your exchange, that coin is gone.
That's another matter of concern. Why would they limit the withdrawals? Obviously, they have some wrong policies that users don't like and if they continue doing that then they will lose so many investors from their platform. If we speculate that situation closely then I think they have changed the minimum withdrawal amount due to the fees of the Bitcoin network, but still it's not fair and many users don't like such limits.
