I am confused about something important ...
Most wallets allow wallet recovery using "Mnemonic phrase", but (in general) with this phrase, do I get access to all my data ? E.g future generated addresses that will hold my bitcoins ?
Another way to ask: is this the only thing I need to store or do I also need to export my actual wallet/keys when I generate a new address or receive new coins ?
I know each wallet works differently but I think this would be a general question. If it matters, I noticed the Mnemonic feature on Electrum and Coinomi wallets.
Edit: how can Coinomi give me access to different coins using same mnemonic phrase ? Does this mean that it is more like a password to my data (data stored by them) and if their wallet service becomes unavailable I don't really have access to any of my different coins ?
