where on Electrum? Receive menu?
if you can be very specific I have no idea what I am doing, it's first time I am using this program and I have no idea about anything else.
I have no idea what I did, it shows me my BTC in my android app! what do I do now?
ha it's because I didn't use WIFI or cellular
You mean BIP49?
On desktop Electrum:
Name your wallet. Click on standard wallet -> I already have a seed -> input the seed phrase and click on 'option' which is below the space you input the seed phrase -> check extend the seed with custom words and select BIP39 seed to proceed. After you click on next, input the passphrase and select the script type. I guess it would be native segwit.
Native segwit bitcoin addresses starts from bc1
Legacy starts from 1
p2sh-segwit starts from 3.
