Altcoin Exchange 101: A Comprehensive Guide on How to Buy and Sell Altcoins


Altcoins came into existence shortly after Bitcoin (BTC) and offered an alternative to the most established cryptocurrency. Now, altcoins account for nearly 80% of the crypto market. Moreover, more than 5,000 altcoins are currently in circulation. On the flip side, investing in altcoins poses a greater risk compared to traditional cryptocurrencies like Bitcoin and Ethereum (ETH). 

Altcoins offer users an opportunity to earn high returns, especially those who know how to squeeze more earnings from the altcoins they already own. Users may consider this a quick guide for first-time investors in altcoins. 

This article highlights the terms in easy-to-understand language and covers different areas, including what an altcoin is, how to buy altcoins on multiple platforms and how to sell them. 

What is an altcoin?

“Altcoin” is short for “alternative coin.” Altcoins comprise all cryptocurrency coins that are not Bitcoin (BTC) and include Litecoin (LTC), Uniswap (UNI), Dogecoin (DOGE), Zcash (ZEC) and Cardano (ADA).

Since Bitcoin’s inception in 2009, a plethora of cryptocurrencies have launched in the space, and others keep sprouting up almost daily. These Bitcoin alternatives began diverging further from the Bitcoin consensus mechanism to include various combinations of privacy features, functionalities and supply schedules.

The altcoin strategy of offering additional functions makes them more enticing and valuable compared to their original counterpart (Bitcoin) and gives them additional utility in the eyes of investors. Some of the most common altcoins in the market at present include the following.

Ethereum (ETH)

Ethereum is the second-largest cryptocurrency after Bitcoin by market cap, and it is the largest altcoin. However, many investors no longer regard it as an altcoin due to its potential for price stability; it is a more risk-adjusted investment than most altcoins and is close to Bitcoin.

Moreover, Ethereum was the first blockchain to launch with smart contracts, in turn giving rise to decentralized finance (DeFi) and the consequent novel financial instruments used at present. Ethereum is thus considered an actual money protocol compared to Bitcoin, which is chiefly transactional. 

Ethereum can also be used to lend, borrow, short, long and so on — none of which can be done on Bitcoin’s base layer. Compared to Bitcoin, Ethereum acts as a ledger on which investors can build decentralized applications (DApps) using their native tokens (ETH).

Litecoin (LTC)

Litecoin is also called the silver alternative to Bitcoin’s gold and is a fork of the original Bitcoin mechanism. It comes with a different hashing algorithm (Scrypt) and has a faster block processing speed, which results in a production capacity of 4x what Bitcoin can supply. However, it’s been dismissed as a redundant (and ultimately unnecessary) Bitcoin fork. 

Stellar (XLM)

Unlike most cryptocurrencies, Stellar focuses on international bank transfers. Stellar leverages distributed ledger technology (DLT) to exchange value across various boundaries and then exchanges the cryptocurrencies into fiat.

Ripple (XRP)

Ripple (XRP) is a popular digital payment platform that hosts crypto coins. It’s also one of the most common cryptocurrencies and uses a consensus mechanism that is different from the traditional proof-of-work (PoW) mining process of Bitcoin.

Uniswap (UNI)

Uniswap is the first decentralized exchange (DEX), and it’s hosted on the Ethereum blockchain. Therefore, Uniswap uses the ERC-20 algorithm native to its platform. Since it is open source, it has spawned several copycat competitors in the space, including Sushiswap (on Ethereum as well) and PancakeSwap (on the Binance Smart Chain). 

Polkadot (DOT)

Polkadot (DOT) is the brainchild of Dr. Gavin Wood, one of the cofounders of Ethereum. Polkadot is a promising blockchain because, like Cardano, much of it is peer-to-peer research-based. But instead of having a testnet on its own blockchain like with Cardano’s testnet on its chain, Polkadot first launches its experimental features on the Kusama chain for testing.

Where can I buy altcoins?

The emergence of numerous altcoins has led to a surge in the development of Bitcoin-altcoin exchange platforms, increasing market activity. However, most investors still struggle with where to buy small-cap altcoins.

“Small-cap” refers to cryptos with a market cap lower than $1 billion. A sound general principle to follow when investing in cryptocurrencies is to arrange them into groups based on market cap. A larger market cap tends to indicate a safer investment, but this is not a hard rule, and user experiences may vary.

Now, many platforms allow traders to buy, hold and sell altcoins. However, each of these platforms comes with different privacy policies and features. Thus, the best altcoin exchange depends on several factors, including buyer preferences.

However, many users have also incurred losses due to scams and bugs that have been exploited on numerous exchange platforms. Therefore, it’s up to every investor to transact on a reputable exchange.

Moreover, if an investor chooses to trade privately with another investor via direct transactions, they should spend some time identifying reliable traders. One of the best ways to protect one’s investments is by conducting significant research on every platform and trader before committing funds.

For new investors, it’s safer to avoid the lesser-known platforms and stick to reputable exchanges like Coinbase, Binance, KuCoin, eToro or

Before making a purchase, users should shop around to review the permitted exchanges in their respective jurisdictions and check the exchange markets to ensure that they have access to the cryptocurrencies of their choice.

It’s also prudent to consider the exchange fees to avoid spending more when there are cheaper options out there.

How to buy altcoins?

The process for buying cryptocurrencies on different platforms may differ slightly, but the steps are mostly similar and fairly straightforward.

While exchanges are safe for beginners and help users avoid fraud, advanced traders may even choose to purchase altcoins from owners over-the-counter.

Steps to consider before buying Altcoins

Step 1. Decide on a percentage of portfolio allocation for the investment

Most altcoins are still in an experimental phase, while many other teams have launched their coins and then vanished after dumping their allocated sums on the market (also known as a rug pull). Thus, a significant percentage of blockchain projects fail pretty quickly.

Purchasing altcoins is a fairly risky investment, and the chances of the coin sinking are relatively high. Therefore, it’s safer to separate a portfolio into different risk layers, especially for investors eyeing lesser-known altcoins.

Step 2: Shop around for the most promising coins

Thousands of altcoins are available for investors. Whether one is suitable for investment depends on several factors, including the investor’s needs and preferences.

Thus, every user should learn more about altcoins that are tied to their favorite projects. They should also examine their various features and select the coins that most appeal to them.

Some critical questions to consider before investing in altcoins

These questions will help guide users to arrive at viable decisions and pick the right altcoin in which to invest.

Step 3: Exchange fiat currency for cryptocurrency

Most exchanges aren’t fiat on-ramp platforms and do not support U.S. dollar purchases. Thus, investors are required to purchase supported cryptocurrencies and then swap them for altcoins on the exchange.

Several exchanges allow the direct purchase of cryptocurrencies via credit card, making it easy to obtain coins for an altcoin exchange. 

Step 4: Pick the right exchange

With a bag of cryptocurrencies ready for trading on an altcoin exchange, investors will have to identify the exchanges that offer their favorite altcoin. New buyers are safer transacting on popular exchanges since they have high liquidity and fewer fraud cases. 

Thus, it’s essential to find different cryptocurrency exchanges that offer a favorable trading pair. Once they identify the trading pair they want, users begin trading their coins. But before executing a trade, here are some critical questions to consider:

  • Is the exchange reputable?
  • Are there any past reports of hacking or bug exploits on the platform?
  • What are their fees compared to competitors?

Step 5: Pick a currency pair

The next step is to connect a Web 3.0 wallet storing the altcoins to the exchange. Before executing the trade, it’s worth noting the trends of the currency pair and its performance over the past month or few weeks to ensure that the user makes the trade at the best time.

Step 6: Execute the trade

If the conditions look promising and the user is ready to make the trade, it’s time to execute. If trading for the first time, invest some time in learning how orders work and then place an order for the desired altcoin on the exchange.

Step 7: Check that the altcoins are already in the wallet

Having executed the trade, the cryptocurrency will already be sitting in the wallet. The only time a user must transfer their funds off of an exchange and to their wallet is when the exchange is centralized. For DEXs, funds are not custodied by the exchange unless they’re provided for liquidity pools, yield farming or some other DeFi tool. 

Crypto wallets are available in two different forms: cold (also called “hard” because they’re hardware) and hot wallets. Cold wallets like Trezor and Ledger are USB-like devices that store a user’s private keys, making it difficult for hackers to control user funds without also having physical access to the hard wallet. 

Hot wallets, by comparison, are connected and hosted online, either via a phone (Trust wallet, for example), desktop (Daedalus) or web app (Metamask). Hot wallets are more vulnerable in terms of security, but lower security affords greater convenience to users.

Regardless, it is in the user’s best interest to familiarize themselves with every platform they plan to use. They should also test out the buying and selling experience.

Every altcoin investor needs a cryptocurrency exchange platform to begin trading. Hundreds of cryptocurrency exchanges are available to users. However, the very best platforms that are reputed to be dependable are few.

Binance also has its coin, BNB, which investors can use to fund transfer fees and offer financial derivatives in select locations.

Are altcoins the right investment for crypto users?

Like investing in anything, investing in crypto assets is no different, and comes with its own set of risks. But high volatility is a given in a new market and presents considerable upside potential compared to traditional markets. While “more stable” altcoins like Ethereum seemingly have reduced risks, there’s no guarantee that an investment will yield greater returns.

Before investing in altcoins, especially the highly volatile options, users should conduct thorough research and invest only what they’re willing to lose. A couple of the benefits that come with investing in altcoins include having more room for growth, and some have interesting utility and present promising use cases.

Users should be aware of a few other risks associated with investing in altcoins. First, there are thousands in the market, and it can be challenging not to overdiversify. Low liquidity may affect slippage and transaction fees, and selling could become problematic later on. Pretty much anyone can launch an altcoin. Home-baked DApps could be susceptible to security exploits. 

What’s next? 

Whether users should invest in altcoins depends on several factors, including the reasons for the purchase, risk averseness and others. As investors say on Wall Street, “Volatility is our friend.” 

A trend to keep in mind is that altcoin prices are still coupled to BTC, so when BTC rises and falls, altcoins tend to follow (after ETH). Still, users should exercise caution when considering an altcoin in which to invest. 

Although altcoins tend to rise in tandem overall, failing projects will only fall eventually. And most new projects can fade pretty quickly. On the other hand, solid altcoin projects like Ethereum, Polkadot, Cardano and Polygon have stood the test of time and warrant closer investor scrutiny. CRYPTOCASTER® - DECENTRALIZED FREEDOM!
