Yeah, Electrum is actually one of the oldest and most respected Bitcoin wallets out there. It’s super lightweight, fast, and secure — but it’s not the most beginner-friendly. It assumes the user knows a little bit about Bitcoin basics (like seed phrases, fees, etc.).

Pros:

• Very secure if downloaded from the official site.

• You control your private keys (non-custodial).

• Fast and lightweight.

• Good for hardware wallet integration later (Ledger, Trezor, etc.).

• Highly customizable (like setting manual fees).

Cons:

• The interface looks a bit old and can be intimidating for newbies.

• It’s Bitcoin-only — no other coins.

• You have to be careful to only download from the real website (there are fake ones around).

For a total beginner in Poland, depending on their comfort with tech, something like BlueWallet (mobile, easier to use, Bitcoin-only too) or Phoenix Wallet (even simpler, lightning-focused) might be a smoother first experience.
