A lot of people lose Myetherwallet wallet, Email. I advise you to store your private key carefully and use 2FA for the account.
Keep your privacy secure and start simple trading by buying coins and then selling will give you profit and try to avoid ICO projects etc and make it a pure trading. Keeping a secure privacy will be safe for you to stay away of these hackers and do not open your wallet in the presence of someone so that he/she may not copy your password so this is of great importance to take care of your privacy.
