The storage wallet is in theory, almost the same in functioning as the Cointree wallet. However, in practical usage it is distinctly different as you will not be able to spend money from it directly. It is used as a system to store coins that come in from individuals making their deposits. It is usually a wallet that is kept offline and payments are sent towards it in batches in order to ensure maximum security. When you make a deposit, we often blend it with the wallets of others. Storage of coins on distributed bitcoin addresses within the community, makes the system fraud-resistant and transparent.
