I have an Electrum wallet and I successfully restored my wallet a few times now from the 12 word seed. My question is: what happens if something goes wrong with Electrum, what if they close down or just disappear for whatever reason and switch their servers off, what happens to my BTC then? Can I restore on another wallet using the Electrum seed?
In simple words if you want to know then it is that you cannot restore your electrum wallet on any other wallet. The only way is to take backup of the Private keys of the address you are using and store them. As with the private keys only you can access the same address on any other wallet.
