In the cryptocurrency world, "SAFU" is a popular term originating from a misspelling of "safe." It gained prominence following a tweet from Binance CEO Changpeng Zhao (CZ), which reassured users that their funds were "SAFU," or safe. Since then, SAFU has evolved into a broader term to assure users that their funds or investments are secure.

SAFU in Practice:

  • Binance Secure Asset Fund for Users (SAFU): Binance established a Secure Asset Fund for Users (SAFU) in 2018. This emergency insurance fund is designed to protect users' funds in extreme cases, such as security breaches or technical failures. A portion of trading fees is allocated to the SAFU fund to maintain stability.
  • General Use: In the broader crypto community, the term is used humorously and sincerely to reassure users about the security measures, whether for exchanges, wallets, or investment platforms.
