How To Protect Yourself from PhishersPhishers send you a message with a link to a website that looks just like MyEtherWallet, EtherDelta, Paypal, or your bank, but is not the real website. They steal your information and then steal your money.
Install EAL or MetaMask or Cryptonite by Metacert or the MyEtherWallet Chrome Extension to block malicious websites.
Always check the URL:
https://www.myetherwallet.com.
Always make sure the URL bar has MYETHERWALLET INC in green.
Do not trust messages or links sent to you randomly via email, Slack, Reddit, Twitter, etc.
Always navigate directly to a site before you enter information. Do not enter information after clicking a link from a message or email.
Install an AdBlocker and do not click ads on your search engine (e.g. Google).
How To Protect Yourself from ScamsPeople will try to get you to give them money in return for nothing.
If it is too good to be true, it probably is.
Research before sending money to someone or some project. Look for information on a variety of websites and forums. Be wary.
Ask questions when you don't understand something or it doesn't seem right.
Don't let fear, FUD, or FOMO win over common sense. If something is very urgent, ask yourself "why?". It may be to create FOMO or prevent you from doing research.
How To Protect Yourself from LossIf you lose your private key or password, it is gone forever. Don't lose it.
Make a backup of your private key and password. Do NOT just store it on your computer. Print it out on a piece of paper or save it to a USB drive.
Store this paper or USB drive in a different physical location. A backup is not useful if it is destroyed by a fire or flood along with your laptop.
Do not store your private key in Dropbox, Google Drive, or other cloud storage. If that account is compromised, your funds will be stolen.
If you have more than 1-week's worth of pay worth of cryptocurrency, get a hardware wallet. No excuses. It's worth it. I promise.
