@owasco you're so cute 🤗 hodl is just a word that the crypto community adopted or make it their jargon for 'hold' as in; hold their crypto/bitcoin/any other altcoins by not selling it (believing that the price will go higher) whenever they saw people panicking looking at the sellers start selling their coin according to the chart graph. I read it was a typo, but then they adopt it as it is.
The same with "safu" for safe; this was from CZ Binance last time as he panicking typing/inform their customer about their fund is safe from the hacking.. then crypto community adopted this word; safu too
