How do transaction costs compare between Bech32 addresses and legacy Bitcoin addresses? Now that Electrum 3 supports Bech32 addresses for segwit, when sending coins to a legacy address are fees higher or cheaper?
Transfer from Legacy ⟶ SegWit: pay full fee (doesn't benefit from SegWit discount)
Transfer from SegWit  ⟶ Legacy or SegWit: discounted.

Note: SegWit addresses can be Bech32 bc1... or they can be nested in a legacy P2SH 3... address which are backwards-compatible (although less efficient). Many exchanges, wallets support the legacy &quot;nested&quot; form only.
