Blockchain.info
Blockchain.info is a
user-friendly hybrid wallet. It stores an encrypted version of your wallet
online but decryption happens in your browser. For security reasons, you should
always use the browser extension and email backups (and keep that email
secure).Hosted control over your money:-
This wallet gives you
control over your bitcoins. However, this service is retaining an encrypted
copy of your wallet. This means your bitcoins can be stolen if you don't use a
strong password and the service is compromised.
Centralized:-
This wallet relies on a
centralized service by default. This means a third party must be trusted to not
hide or simulate payments.
Remote app:-
This wallet is loaded from
a remote location. This means that whenever you use your wallet, you need to
trust the developers not to steal or lose your bitcoins in an incident on their
site. Using a browser extension or mobile app, if available, can reduce that
risk.
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 on 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 information to a third party:
This service can associate
your payments together, log your IP address and know your real identity if you
provide personal information like your email, name or banking account.
Tor can be used:
This wallet lets you setup
and use Tor as a proxy to prevent attackers or Internet service providers from
associating your payments with your IP address.
