People are still using web wallets really? Did we not learn from blockchain.info.
What's wrong with blockchain.info?
People still get hacked on blockchain, but they are a lot better than most web wallets, and if they add trezor support like they plan on, they will be the most secure web wallet.
I think blockchain.info will probably be safer for a newb who doesn't really know waht they're doing, as long as they set up all the security features; 2 factor auth and a second password etc.
I have heard about people getting hacked on blockchain.info when not using 2FA, but I haven't heard of a single hack from a person that uses 2FA. I consider it extremely safe.
As far as Bitgo is concerned. I use it too and like it as a service. I feel more confident that a webwallet isn't going to run off with my money when it was designed from the ground up to be impossible to do that. Now maybe that is or isn't the case in reality and we don't always know what a sneaky hacker will do. Still.... I have used Bitgo and feel confident with it.
And always use 2FA when possible!
