Hi

I still have a Wallet but I needed to create a new one. So, I did. But no BTC in it. I created a BTC adress to receive and saved it with a name and created a Backup of this new wallet. So. I was waiting to receive a little value but the BTC address was invalid. When I logged into this new wallet, I verified that the Address hase not been saved, but I´m sure it was.

Did I make something wrong?

Hi Sauaba,
I'm sorry to say I'm having a hard time understanding you, and based on the two responses above, I don't think I'm the only one. It may help us if you find another way of describing your situation.

From what I can gather, you created a new wallet in Electrum, but were unable to use that address. Does the new address start with b1c? If so, that may be your problem. Some exchanges and custodial wallets do not support those typed of addresses yet. You can try creating a new wallet, and instead of choosing a native segwit wallet (p2wpkh) chose the p2sh-segwit (p2wpkh-p2sh). Electrum will create a wallet with addresses that start with the number 3. Those will be compatible with any exchange or another type of wallet.
