The last few days. The fluctuations are great. It takes a long time to charge between the two exchanges, and the market may continue to fall during recharge. So it is not recommended to do so.
This is huge gap between such exchanges but one need to be careful and understand that how much time will it take currently to deposit and withdraw the money as exchanges with be flooded with request as everyone would like to take the pie of it. It should not happen that your money gets struck and by the time it is deposited the market has already bounced back and not really worth buying later.
