One of easiest way to create and access Ethereum and erc20 token is MEW web interface. My question is , is it safe to keep big amount in MEW or better not to rely on it.
If you can protect your MEW account, it is safe to store your ethereum and erc20 token in that wallet.
But you should not forget that the hacker will try to search for the bugs to penetrate the MEW wallet and steal your tokens.
To avoid that, you should move your token, and sell the coin will be better if the price can reach the high price to transfer your ethereum to the other wallet.
I do not want to store a big amount in MEW because I am afraid of the hacker, and I think it would be good to get it on a separate wallet, which we can know is safe.
