Qui un articolo su Bitcoincore che chiarisce i vari benefici del segwit

Electrum 3 is probably the first wallet to support native segwit (bech32) addresses. There are a few misconceptions regarding the different formats of segwit addresses that are in use right now. This post aims to clarify the consequences of using each type and explains advantages and disadvantages.
bech32/BIP173/"native segwit"
Bech32 is a brand new address format that has a few advantages over the current address format:
Addresses are case-insensitive
Better error detection
More compact QR codes
Most importantly, bech32 segwit addresses enable native segwit transactions for Bitcoin. Those addresses always start with bc1.
However, since bech32 addresses are still quite new (the proposal is still in "Draft" state), most wallets, exchanges and payment providers do not support sending to those addresses yet.
What you can do with a wallet that uses these addresses:
send to any and all wallets, exchanges and websites
receive from other Electrum wallets version 3.0 or greater
What you cannot do with such a wallet:
receive from most other wallets and websites simply because they consider bech32 addresses as invalid.
To use these addresses, simply create a new wallet and choose "Segwit" as the seed type in the creation wizard.
segwit-in-p2sh/P2SH-P2WPKH
This is the address type that hardware wallets like Trezor or Ledger use. Addresses look like regular P2SH addresses, they start with 3. Without going into too much detail, this uses an old address type and uses segwit to spend from it. The advantage is that virtually all wallets already know how to send coins to this kind of address. One disadvantage is that to spend from those addresses, additional complexity is added to the transaction which makes those transactions slightly bigger (and thus more expensive) than native segwit transactions.
Electrum also supports this kind of addresses but you need to manually import a BIP39 seed with a BIP49 derivation path.
Secondo me ora se si ha la possibilità conviene usare direttamente i segwit.
Tra l'altro se non sbaglio Bitstamp, uno dei maggiori exhcange, supporta già questi indirizzi.
