The minimum amount that you can deposit is 0.005 BTC or 0.1 ETH. If your deposit is lower than that, the amount will not be reflected in your wallet balance. 

To be able to see or use your funds, you will have to make a deposit that is equal or higher than the minimum amount. For example, if you attempt to deposit 0.003 BTC, you will need to make another deposit for at least 0.002 BTC before the total 0.005 BTC will be reflected in your wallet balance.
