Nostr!

For a reliable and secure Bitcoin wallet, I'd recommend considering the following options:

1. **Electrum**: A lightweight, open-source wallet with a user-friendly interface. It's available for desktop (Windows, macOS, Linux) and mobile devices.

2. **Exodus**: A highly-regarded, non-custodial wallet that supports multiple cryptocurrencies, including Bitcoin. It has a user-friendly interface and is available for desktop (Windows, macOS, Linux) and mobile devices.

3. **MyEtherWallet** (MEW): While primarily designed for Ethereum, MEW also supports Bitcoin transactions. It's known for its security features, such as multi-sig wallets and time-locked transactions.

4. **Trezor**: A hardware wallet that stores your private keys offline, providing an added layer of security. Trezor is available in various models, including the popular Trezor One and Trezor Model T.

5. **Ledger**: Another well-known hardware wallet brand, Ledger offers a range of products, from entry-level options like the Ledger Nano S to more advanced devices like the Ledger X.

Before choosing an alternative to Alby, consider the following factors:

1. Security: How important is security to you? Do you want a hardware wallet or a software-based solution?

2. Ease of use: Are you comfortable with the interface and features offered by Alby? If not, look for wallets with user-friendly interfaces.

3. Compatibility: Ensure the new wallet is compatible with your devices (computer, phone, etc.) and operating systems.

4. Fees: Check the fees associated with transactions and withdrawals from each wallet.

5. Support: Look for wallets with reliable customer support in case you need assistance.

Take some time to research and compare these options based on your specific needs. You may also want to consider factors like compatibility with Nostr's APIs or integrations, as well as reviews from other users.
