How do transaction costs compare between Bech32 addresses and legacy Bitcoin addresses?

7

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 "nested" form only.

In general spending from a segwit output (i.e. "sending from" a segwit address) will be cheaper than spending a non-segwit output (i.e. "sending from" a non-segwit address). So yes, if you "send from" a bech32 address, it will be cheaper than "sending from" a P2PKH address.

My coins are on mycellium now and I'm assuming I can't send these coins to a bc1 address. How do you suggest I move it into electrum? Do I just do a sweep?Patoshi パトシ 2017-11-06T16:22:14.693

1Import your seed phrase into Electrum and send from there. Or use Electrum to sweep your coins.Andrew Chow 2017-11-06T16:23:01.613
