wow...the keys are constantly rotated? how long the keys rotate? if I change the dves the keys will rotate? if this is the case how can I make sure my coin safety? do not change dves? constantlty backup?
I think dves means hubs.
You will not lose bytes by changing hubs. You can change all you want and never worry about losing bytes.
If you change hubs, you risk losing messages (like how private assets (blackbytes)) are sent.
Also, to ensure safety against losing blackbytes to be sent (like from a distribution)(other than simply not playing around by changing hubs), you can talk to the transition bot after you change hubs.
To prevent from losing blackbytes/assets you already have, then simply make full backups (not just a backup from of the seed).
