You know, I often see newcomers in crypto getting lost in the flood of information. FOMO, HODL, ATH – these abbreviations are everywhere, and people just don’t understand what’s behind them. I decided to figure it out myself and noticed that many can’t even distinguish between altcoins, meme coins, and total scams. Let me share what I’ve learned.

Let’s start with basic terms that come up all the time. FOMO is simply the fear of missing out. When you see a coin rising and feel the urge to jump on the bandwagon. HODL is a funny story – it was a typo of the word hold, but the crypto community turned it into a philosophy of long-term holding. Opposite market states are also important: a bull market is when everything is going up, a bear market is when it’s falling. ATH (all-time high) and ATL (all-time low) help understand where the price is relative to extremes.

There are characters called whales – those who hold large volumes. They can move the market with a single transaction. Pump and Dump is manipulation where the price is artificially inflated and then dumped. It’s important to spot these schemes.

Now about technologies. DeFi stands for decentralized finance – a whole ecosystem of applications without intermediaries. Staking is when you lock your tokens and earn rewards for participating in the network. Mining is the process of generating cryptocurrency through computations. Liquidity pools are when people deposit tokens into a contract to facilitate trading and earn commissions. Yield farming is a more advanced strategy for earning income through DeFi.

ICO used to be a way to attract investment for a project, but now it’s almost obsolete. DEX (decentralized exchange) operates without a central owner, through smart contracts. CEX (centralized exchange) is a traditional platform run by a company. Fiat refers to regular government-issued money.

Security is a key topic. A wallet stores your cryptocurrencies. Private Key is your password that you never share. Public Key is your address, which you can share freely. Seed Phrase is a set of words for restoring your wallet; keep it safe as gold.

Smart contracts are programs that automatically execute conditions. Gas fees are transaction fees on networks like Ethereum, measured in Gwei. NFT stands for non-fungible tokens, unique digital assets.

Fraud is also important to know. Rug Pull is when developers take the money and disappear. Rekt is when you lose a significant amount of money. Shill is when someone actively promotes a project. FUD is spreading fear and uncertainty. DYOR means do your own research, don’t blindly follow others. BTD/BTFD – buy the dip, a classic strategy.

Project metrics: APY shows annual yield, TVL (Total Value Locked) indicates how much money is locked in a DeFi protocol. KYC and AML are rules for exchanges to know their customers and fight money laundering.

Organizational structures: DAO is a decentralized autonomous organization managed by the community through voting. CBDC is a central bank digital currency, representing the future of government-issued money.

Technology evolves in layers. Layer 1 is the main blockchain, like Bitcoin or Ethereum. Layer 2 are solutions built on top of the main network, like Arbitrum, Optimism, Base, which speed up transactions. Cross-chain protocols enable interaction between different blockchains. Oracle is a system that provides real-world data to smart contracts.

Airdrop is a free distribution of tokens to the community, often to attract users. Soft fork is an update compatible with previous versions. Hard fork is an update that splits the network if there’s disagreement.

Mining details: block reward is the amount of crypto a miner receives for finding a block. Hash rate measures the network’s computational power. Satoshi (SATS) is the smallest unit of Bitcoin, 100 million satoshis = 1 BTC.

Now about coin classification, where the interesting part begins. Altcoins are simply everything except Bitcoin. They appeared to improve certain functions or add new features. Ethereum introduced smart contracts, others sped up transactions or lowered fees. Some focus on DeFi, others on specific applications. LFG reflects enthusiasm for altcoins – eagerness to move forward and believe in their potential.

Shitcoins is a more blunt term for altcoins that seem empty. No innovation, just copy after copy. Their prices move on speculation and hype, not technology. Developers may lack long-term plans. The risk of manipulation is high, transparency is low. These are high-risk investments that can easily be lost.

Meme coins are a different beast. They originate from internet culture, memes, humor. Dogecoin is a classic example, started as a joke about Shiba Inu. But then a community formed around it, and people began using it. Even Elon Musk once supported it. Meme coins live on community energy, and their prices are wildly volatile. They have no practical use at the start; they’re entertainment. But internet hype can create real value.

There’s even a subdivision: land dogs – these are young meme coins, unknown projects at the bottom of the hierarchy. Golden dogs are when a meme coin skyrockets by tens or hundreds of times and becomes popular. Shiba Inu was positioned as Dogecoin’s killer, PEPE became famous. When such a coin gains momentum, the community calls it a golden dog, gaining recognition.

Air coins are a red flag. These are cryptocurrencies without real backing, no use case, often scams. They exist only in words and hype. No solid foundation. Their price is maintained only through manipulation and propaganda. Investing in them is like Russian roulette. The teams are opaque, processes hidden. Such coins can disappear overnight when hype fades.

The simple conclusion: before investing in any project, you need to really understand it. Study the technology, team, market position, and risks. Not all altcoins are shitcoins, not all meme coins are air coins. But not everything that glitters is gold either. LFG is the spirit, but smart LFG also means DYOR, your own research. The crypto world is full of opportunities, but also plenty of traps.
