Therefore, if we have a lot of Ethereum or token. We should have a Hardware Wallet for safer security. Chances are our funds will be safe from such problems.
Correct, you must choose safety rather taking the risk of putting it up on web wallet such as MEW because we can't tell and predict what will happen.
This is a good experience that no one did predicted before so we did learned from this incident especially to those who are trusting much MEW.
Hackers are everywhere so you have to choose the best way to store your ETH or tokens.
I guess everything's good and calm now with MEW.
