Encrypt the amount of syscoin visible in the wallet before unlocking it (improvement)

[Redranger696]

Due to Blockmarket being far more than a wallet I see it being convenient for the masses to disclose the amount of sys there is in their wallet before unlocking it. In this way they can search the marketplace, check certificates etc without the need to hide anything from their surroundings. Something like blockfolio has done. This may not seem like an important future for now, but it makes Blockmarket more convenient to use for those not wanting to create several wallets to seperatly store their sys for this reason. Leaving the banking era, this feature will help with creating more security for the self instead of handing the trust out to others.
