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.
MEW never save your money, it just an tools to interact with your wallet in the Blockchain.
Just make sure when you access your wallet with Private Key or anything else, you connect to a Correct MEW site, make sure its https and the domains is correct.
