Hello, I had coins on Electrum wallet, but now there are 0 coins .. Will they appear in the new wallet?
it is not 0 coin. I mean (IM NOT SURE) Electrum wallet wipe your original wallet and now you have empty wallet with zero coins
Now I find my backup seed and restore my electrum wallet - still 0 coins.
Eletrum depends of servers. It's just a way to read your balance on the chain. As long as you have your pass + seed, nothing is lost.
