HODL, sometimes spelled out hodl or Hodl, started as a joke at a bitcoin fan's expense.
In December 2013, a member of the official bitcoin message board made an apparently inebriated post with a typo in the subject line: "I AM HODLING." He was trying to say that he's "holding," as in, hanging on to his coins for the long term, regardless of any short-term price changes.
The post became a meme, as bitcoin fans retroactively made it so HODL stands for "hold on for dear life." The term is used to discourage selling when bitcoin prices fall, and to ride it out until they return to growth.. It's viewed as a faux pas in the cryptocurrency community to sell instead of holding on for dear life.
"To the Moon" is an exclamation used when cryptocurrency prices are rising off the charts. By the same token, when a coin's price is "mooning," that means that the price has hit a peak. You might ask the grammatically-incorrect question "when moon?" if you wanted to know the opportune time to sell your cryptocurrency, before prices go back down.
Many Bitcoiners are all about making money quickly. "When Lambo" translates to "when will you buy a Lamborghini?" Which is to say, when will you get ridiculously rich off of bitcoin?
Hyperbitcoinization is the word used by some bitcoiners to describe their ideal outcome: When regular currencies are devalued, and replaced by bitcoin and other cryptocurrencies.
According to The Merkle, Obsessive Cryptocurrency Disorder, or OCD, is a condition developed over time by those who own any amount of bitcoin. They become obsessive about watching bitcoin prices rise and fall, all day and night.
"Fear, uncertainty and doubt," shortened to "FUD," isn't a term exclusive to the bitcoin community.
Among bitcoiners, however, FUD is generally used to refer to anything, like negative press coverage or blog posts, that might dissuade people from joining the cause of cryptocurrency.
Otherwise, FUD can mean a number of other things, including the practice of hyping up a cryptocurrency you own to drive its price higher, or sowing discord among owners of another coin so you can drive the price down and buy it cheap. Sometimes, it just means "Facts U Dislike."
When a bitcoin holder (or HODLer) is mocked for not being rich yet, they're being bitshamed. The case of bitcoin advocate Andreas Antonopoulos is a great example of this. An avid bitcoin lecturer for years, he revealed in December that he's actually not a bitcoin millionaire, and sold his coins early to cover rent and bills. He was bitshamed by Roger Ver, known in the bitcoin community as "Bitcoin Jesus," for his failure to hodl.
A nocoiner is a person without bitcoin — an outsider that scoffs at cryptocurrency and all those who relish in it. While it can be used for anyone who doesn't hold any cryptocurrency, it's usually reserved for cynics and skeptics.
A bitcoin maximalist believes that bitcoin, not any other cryptocurrency, will take over the world. They're all about hyperbitcoinization.
An altcoin, as the name suggests, is an alternative cryptocurrency to bitcoin. Since bitcoin was the first cryptocurrency, anything that pops up after it is dubbed an altcoin. Most altcoins take their cues from bitcoin, but with subtle technological tweaks. Popular altcoins include ethereum, Ripple's XRP, and litecoin.
Derived from the word "wrecked," you might say that a cryptocurrency investor got rekt when they made a bad trade, like selling their bitcoin right before the price skyrockets upwards.
"Do your own research" (DYOR) is a common pearl of wisdom: If you're told to DYOR, it means you should think for yourself and draw your own conclusions, rather than following the wisdom of the crowd — or lack thereof. Failure to DYOR can get you rekt.
#DYOR but also if someone else is well-informed about crypto, it's okay to take their advice. Some are experts, some are just guessing. Coins I mention are coins in my portfolio. Take my non-financial gambling advice- this year is going to be huge 🚀🚀$EOS$LTC$LRC$ICX$ZRX
A whale, or a crypto whale, refers to a top player in the crypto market. These people hold a substantial amount of coins, accounting for a small fraction of cryptocurrency users. When a whale buys or sells, their influence is so strong that they may move the market.
Cryptocurrency fans actually borrowed the term bagholder from Wall Street.
On the stock market, it describes an investor who holds on to their shares in a company for too long and ends up taking a huge loss when the value tanks. In cryptocurrency, it basically means the same thing — if you buy a bunch of altcoins, and wait too long to sell, their value could go to zero, and you're left holding the bag.
