Mac
Control over your money
This wallet gives you full control over your bitcoins. This means no third party can freeze or lose your funds. You are however still responsible for securing and backing up your wallet.
Simplified validation
This wallet uses SPV and the Bitcoin network. This means very little trust in third parties is required when verifying payments. However, it is not as secure as a full node like Bitcoin Core.
Basic transparency
The developers of this wallet publish the source code for the client. This means any developer in the world can audit the code. However, you still need to trust developers of this wallet when installing or updating the final software because it was not built deterministically like Bitcoin Core.
Vulnerable environment
This wallet can be loaded on computers which are vulnerable to malware. Securing your computer, using a strong passphrase, moving most of your funds to cold storage, or enabling two-factor authentication can make it harder to steal your bitcoins.
Weak privacy
Allows spying on your payments
This wallet makes it easy for anyone to spy on your balance and payments because it reuses the same addresses.
Discloses limited information to peers
Peers on the network can log your IP address and associate your payments together when receiving or sending payment.
Tor not supported
This wallet does not let you use Tor to prevent attackers or Internet service providers from associating your payments with your IP address.
Static fee suggestions
This wallet does not provide any fee suggestions which are based on current network conditions. This means that your transactions may be subject to delays if the fee chosen is too low, or that you may pay a fee which is too high.
Take time to educate yourself
Bitcoin is different from what you know and use every day. Before you start using Bitcoin for any serious transaction, be sure to read what you need to know and take appropriate steps to secure your wallet. Always remember that it is your responsibility to choose your wallet carefully and adopt good practices in order to protect your money.
