              With each subsequent block that is found, the number of confirmations is increased by one. To protect against double spending, a transaction should not be considered as confirmed until a certain number of blocks confirm, or verify that transaction.

                <b>No</b> (default, recommended) - will allow to recycle spacecoin addresses that been generated for each placed order but never received any payments. The drawback of this approach is that potential snoop can generate many fake (never paid for) orders to discover sequence of spacecoin addresses that belongs to the wallet of this store and then track down sales through blockchain analysis. The advantage of this option is that it very efficiently reuses empty (zero-balance) spacecoin addresses within the wallet, allowing only 1 sale per address without growing the wallet size (Eletrum "gap" value).
                <br />
                <b>Yes</b> - COMMING SOON. This will guarantee to generate unique spacecoin address for every order (real, accidental or fake). This option will provide the most anonymity and privacy to the store owner's wallet. The drawback is that it will likely leave a number of addresses within the wallet never used (and hence will require setting very high 'gap limit' within the Electrum wallet much sooner).
                <br />It is recommended to regenerate new wallet after number of used spacecoin addresses reaches 1000. Wallets with very high gap limits (>1000) are very slow to sync with blockchain and they put an extra load on the network. <br />
                Extreme privacy mode offers the best anonymity and privacy to the store albeit with the drawbacks of potentially flooding your Electrum wallet with expired and zero-balance addresses. Hence, for vast majority of cases (where you just need a secure way to operate spacecoin based store) it is suggested to set this option to 'No').<br />
