I have tried Blockchain, Electrum, Mycelium and Armory but they all have a same risk of losing your keys whenever a device is factory restored. And due to my forgetful nature I may also forget where I hid their corresponding backup keys.

Thus to prevent complications, I ordered a Ledger Wallet where one can securely initiate and validate a transaction either with the "second factor authentication card" or by "smartphone pairing".

In any case my device needs a reset, I can easily import my previous wallet just by entering a set of passphrase. (provided during initial setup)

Moreover if someone steals that ledger he can't do anything since he'll try brute forcing the password and right after 3rd attempt the wallet will erase every keys that were associated before.

Now isn't that secure enough?

Even the best technically advanced wallet is not good when you can't manage your own coins. If you did not copy your keys, if you don't have a good password, or your storage machine will be compromised directly.
Other that that is matter of personal preference (full blockchain vs simplified validation wallets) etc.

Copay FTW compared to those.

Ahh I see, thank you all for responding to my question about blockchain.info

You guys are really helpful, I don't hold a lot in my online wallets. Knowing this now, I might consider to change online wallets.

so what is the best wallet its depends on your security, Im use blockchain.info
i ever receive mailer phising blockchain, i dont know if that is phising, my wallet stay safe because im use sms verify

I have only used blockchain.info and coinsbase so far

I'm using coinbase more than blockchain, I haven't had any issues with neither but I just prefer coinbase better

+1
Same experience here
I also have Core running in another computer that is always on, mostly to help the network

for most users, it doesn't make that much difference which one of the main wallets you use

I registered a GreenAddress account yesterday and I am really liking it so far. The best features to me are the option for a quick login from any device with a PIN number if you are in a hurry and the possibility to access your funds elsewhere if GreenAddress service happens to be offline at the moment. So my vote goes to GreenAddress.

Im also using blockchain as well and so far im its easy to use there there is a 2FA that you can use so that you wallet wont be hacked by anyone.
