What kind of address is more secure to store bitcoin legacy or segwit Every wallet supports different address types. What kind of address is more secure to store bitcoin legacy or segwit? I think some exchanges follow different address formats
None of them are better or worse with regards to its security. Typr of Bitcoin doesn't affects its security but rather its structure. The only difference with them is that the transaction fee with segwit is cheaper than the legacy. Most of secured wallets such as Ledger are now using segwit address instead of legacy which obviously because it's cheaper thus it's a great choice to be considered.
