I prefer electrum cause i have a weak memory and already lost a ledger one time,but is it really safe ?
does something like that hacking of the fake update links showing for people with old electrum clients can happen again ?
Ledger and Trezor can give you the option to hold altcoins, but you want to hold only Bitcoin right? Electrum can be perfect for that. You can learn how to create
Electrum offline wallet. If your airgapped Electrum wallet remain airgapped, then your private key is offline. But just always be careful of clipboard and QR code malware just like in case of hardware wallets.
