#StaySAFU is the principle of ensuring asset safety in cryptocurrency transactions, popularized by Binance. SAFU encourages investors to proactively protect their assets: enable 2FA authentication, avoid linking strange wallets, and do not share the private key. In Vietnam, where crypto is developing strongly, choosing a reputable exchange with a SAFU insurance fund helps reduce the risk of hacking or fraud. Despite market fluctuations, the principle of "never invest more than you can afford to lose" and always updating your security knowledge are the keys to "stay SAFU" – safe from all risks.
