- Prices start at ~$50 (200 PLN).
Software Wallets (Mobile/Desktop Apps)
- Balance between security and convenience.
- Free to use; supports sending/receiving crypto easily.
Online/Web Wallets
- Managed by third parties; avoid storing large amounts due to security risks.
Paper Wallets
- Physical printouts of private keys or seed phrases for backup.
