Byteball allows u to secure your bytes and blackbytes without having to make a single backup. Simply setup a multidevice wallet, for example install Byteball on 3 devices, your phone, your laptop and a loved one's phone or laptop and make sure only 1 is enough to sign (so setup 1 out of 3) so that if any device gets lost you can still sign. Also make sure all your wallets on different devices are synced fully from time to time as otherwise you may not have a full copy of your Blackbytes on all devices. This is also a good way to get loved one started by setting up a wallet for them too that you can also control. Do not forget to setup a different password on every device the moment you start having some serious funds.
