Awesome Privacy

An open source, native desktop wallet for Windows, Linux, and MacOS. Wasabi implements trustless CoinJoins over the Tor network. Neither an observer nor the participants can determine which output belongs to which input. This makes it difficult for outside parties to trace where a particular coin originated from and where it was sent to, which greatly improves privacy. Since it's trustless, the CoinJoin coordinator cannot breach the privacy of the participants. Wasabi is compatible with cold storage and hardware wallets, including OpenCard and Trezor.

Open source, cross-platform, offline, crypto wallet, compatible with 1000+ coins. Your private key is generated on the device, and never leaves it, all transactions are signed by the Trezor, which ensures your wallet is safe from theft. There are native apps for Windows, Linux, MacOS, Android, and iOS, but Trezor is also compatible with other wallets, such as Wasabi. You can back the Trezor up, either by writing down the seed, or by duplicating it to another device. It is simple and intuitive to use, but also incredibly customizable with a large range of advanced features.

An easy-to-use, super secure Bitcoin hardware wallet, which can be used independently as an air-gapped wallet.

Companion products for the ColdCard include: BlockClock, SeedPlate, and ColdPower.

Long-standing Python-based Bitcoin wallet with good security features. Private keys are encrypted and do not touch the internet and balance is checked with a watch-only wallet. Compatible with other wallets, so there is no tie-in, and funds can be recovered with your secret seed. It supports proof-checking to verify transactions using SPV, multi-sig, and add-ons for compatibility with hardware wallets. A decentralized server indexes ledger transactions, meaning it's fast and doesn't require much disk space. The potential security issue here would not be with the wallet, but rather your PC - you must ensure your computer is secure and your wallet has a long, strong passphrase to encrypt it with.

Atomic is an open-source desktop and mobile-based wallet, where your private keys are stored on your local device, and do not touch the internet. Atomic has a great feature set, and supports swapping, staking, and lending directly from the app. However, most of Atomic's features require an active internet connection, and Atomic does not support hardware wallets yet. Therefore, it may only be a good choice as a secondary wallet, for storing small amounts of your actively used currency.
