#StaySAFU

The hashtag #StaySAFU is a common expression in the crypto (digital currencies) communities and the cybersecurity field, meaning:

"Stay Safe" or "Be Safe".

The word SAFU started as an internet joke (meme) but evolved into a term used in digital currency communities to mean "safe," and it is an informal abbreviation for the word "Safe." The first to use it in this way was the Binance platform, which launched the "SAFU Fund" to protect users' funds.

So if you see someone writing #StaySAFU, they likely mean:

> "Take care of your security, do not share your information, verify sources, do not fall for scams."
