In my opinion, the security of online blockchain wallets is equal to hardware wallets. I checked the security of this wallet and it even has special features in terms of privacy, for example for depositing bitcoin every time it offers a new public address, which makes those who track the wallet balance can not complete Find out the inventory of a blockchain wallet and this is not even observed in some exchanges and they always provide a wallet address to the user for deposit.
The ability to import wallets is also very good and you can easily manage the wallet balance in this professional online wallet.
Of course, if you are someone who wants to keep both your money and profit on your wallet balance, it is better to use wallets that offer profit, but for those who are just looking to keep in a very safe environment, Blockchain wallet is one of the best.
