Why is it that when trying to create a segwit address, Electrum is providing me a receiving address starting with bc1 and not 39 like my Trezor does? Reading the rest of this thread it looks like I have to create a segwit address somewhere else and then import it into Electrum?
Electrum only supports the creation of bech32 Segwit Addresses (the one starting with bc1) and Legacy Addresses (starting with a 1). For now, the bech32 addresses aren't supported in many places, which means that most services won't allow you to withdraw to this kind of address - which is why it's not recommended to use this kind of address until people start supporting them.
Read the previous posts to know how to create and import a Segwit wallet that generate addresses starting with a 3 (not 39) in Electrum;
And will that be view only? Thanks!
If you import with the seed, you will be able to spend the coins.
