Hello, I have done a lot of searching to see if I can find the answer to this question (which, is probably a stupid question, but I don't want to (potentially) lose funds because I've done something wrong) but one of my customers recently suggested that I switch to using segwit to lower the fees I pay when paying btc to my suppliers. I will admit, I've used bitcoin for a while now (using electrum wallet) but that's as far as it goes, I use it to pay and recieve funds - I don't know anything about it other than that.

Basically, I've set up a new wallet in electrum and I selected SegWit for it which gave me a bc1 address (which I believe is native segwit) and I know there is some limitation in receiving funds from wallets and services that don't support native segwit... which I'm fine with, I can use the legacy wallet addresses for when this is an issue.

What I want to know is can I send funds FROM my segwit bc1 address TO both legacy and wrapped segwit addresses without issue? I don't want to try and send funds from my bc1 address to an address that starts with a 3, only to have it get lost in the ether.

Secondly, is it possible to transfer funds between my two wallets, which are on the same computer, locally... without sending and having to pay fees?

Thanks for any help and info.
