In my Mavro after I deposit – why the amount in INR is less?

The amount shown in your Mavro after deposit – is the amount calculated according to the rate of Sell Mavro on that particular date. That means if you request to sell your Mavro before 1 month since you bought Mavro at the rate of 30% or before 3 months since you bought Mavro at the rate of 40% -  when you sell Mavro, it will be as per the rate of sale on that particular date. Rates of purchase and sale are different.
