In the crypto world, there are four terms that are common in the communities:

**HODL** - First of all, this is a way of saying 'hold onto your assets' without selling them, no matter what happens in the market. It originated from a typo on a phone, but now it’s a determined attempt to keep your cryptocurrency even when prices are falling.

**BUIDL** - The second term, meaning 'build'. People encourage developers and innovators to focus on creating real projects rather than chasing after prices.

**SAFU** - SAFU here is the third, indicating that your digital money is secure. It reflects the ongoing concern for the safety of wallets and custody houses in the sector.

**DOYR** - Finally, "Do Your Own Research" - do your own research. Crypto communities always encourage people not to follow every piece of advice blindly, but to study the facts themselves before making decisions.
