Most of us started his crypto carreer with a blockchain wallet, and even it has been there since long time running without problems, it was always recommended to not trust web-wallets (in general) as it can be hacked or phished at any time. I didn't have any problem while using this wallet but i want to focus on the detail that my private data (email+password+id) is stored somewhere in their servers and there is no single garantee that nobody has access to it ; it's inaccurate , imo , for anybody to get a crypto wallet using his email, as the wallet can be generated without the need of those information. We should not trust blockchain wallet or any web wallet to store big amounts. However, it's recommended to use the mobile version of blockchain wallet for daily use and micro paiements, as it doesn't recommended to create an account using personal information.
