The best cryptocurrencies for beginners are usually assets with long mainnet histories, published supply rules, and predictable transfer mechanics. This guide compares eight of them: Bitcoin, Ethereum, Cardano, Solana, BNB, XRP, Chainlink, and Tether (USDT), a dollar-pegged stablecoin. For each one, you will see how it works, what you pay to send it, and the network rule a first-time user needs to know. For a broader framework on evaluating coins, read our guide on how to find the best crypto to buy.
Coin | Role | Mainnet launch | Supply model | Fees paid in | Beginner watch-out |
|---|---|---|---|---|---|
Store of value, payments | 2009 | Fixed cap of 21 million BTC; issuance decreases through halvings | BTC | Fees vary with network demand and transaction size | |
Smart-contract platform, payments | 2015 | No fixed cap; new ETH goes to validators while part of fees is burned | ETH | Gas depends on gas used and current network fees | |
Payments, smart contracts | 2017 | Fixed cap of 45 billion ADA; reserves released through protocol rewards | ADA | Fees depend on transaction size; smart-contract transactions add execution costs | |
Low-fee smart-contract platform, payments | 2020 | Uncapped, inflationary supply with protocol-defined issuance | SOL | Priority fees can raise costs when block space is in demand; new token accounts need a small refundable SOL deposit | |
BNB Chain gas token, payments | 2017 (token); 2020 (BNB Smart Chain mainnet) | Auto-Burn targets 100 million BNB, plus real-time fee burns | BNB | The old Beacon Chain shut down in December 2024, so transfers use BNB Smart Chain or another BNB Chain network | |
Payment-focused ledger | 2012 | Fixed original supply of 100 billion XRP; fees are destroyed | XRP | Transfers to exchanges may require a destination tag; a new address needs at least 1 XRP to activate | |
Oracle and infrastructure token | 2017 (token); 2019 (mainnet) | Fixed cap of 1 billion LINK | Network gas token (ETH on Ethereum) | LINK is a token, so sending it on Ethereum requires ETH | |
Dollar-pegged stablecoin | 2014 | Issued against reserves; supply changes with issuance and redemption | Gas token of the chosen network (ETH, TRX, SOL) | Sender and recipient must use the same network |
The tokens above are available on SwapSpace. This is not a recommendation to buy or trade.
Coin | Smallest unit | Minimum to activate or receive | Token standard |
|---|---|---|---|
1 satoshi = 0.00000001 BTC | No account minimum; very small outputs can be rejected as dust | Native coin | |
1 wei = 10⁻¹⁸ ETH (gas is quoted in gwei, 10⁻⁹ ETH) | No account minimum | Native coin | |
1 lovelace = 0.000001 ADA | Each transaction output must carry a protocol-set minimum amount of ADA | Native coin | |
1 lamport = 0.000000001 SOL | New accounts must hold a rent-exempt balance; a token account needs about 0.002 SOL, refunded on closing | Native coin | |
10⁻¹⁸ BNB (18 decimals) | No account minimum | Native coin of BNB Smart Chain (BSC) | |
1 drop = 0.000001 XRP | 1 XRP base reserve to activate an address, plus 0.2 XRP per owned object | Native coin | |
10⁻¹⁸ LINK (18 decimals) | None, but sending requires the network gas token | ERC-20 token on Ethereum | |
0.000001 USDT (6 decimals on Ethereum, Tron, and Solana) | None, but sending requires the network gas token | ERC-20, TRC-20, SPL, and others |
We looked for assets whose rules a first-time user can understand and check in official documentation. Each asset on this list meets these criteria:
We excluded meme coins, privacy coins, and assets with fewer than five years on mainnet. We also kept only one dollar stablecoin, because a second one works the same way from a beginner's point of view. The order below is a presentation choice, not a ranking.
Bitcoin is the first cryptocurrency, launched in 2009. It is a payment network and a fixed-supply asset that runs on Proof of Work (PoW) mining. Its rules are short and stable, which makes it a common starting point for learning how wallets, addresses, and fees work. The Bitcoin FAQ covers the basics.
Ethereum launched on July 30, 2015, as a platform for smart contracts, the programs behind decentralized apps and most tokens. ETH pays for every transaction on the network, including transfers of tokens such as USDT and LINK. Ethereum moved to Proof of Stake (PoS) in September 2022, according to ethereum.org.
Cardano launched in 2017 as a payments and smart-contract blockchain. It uses an extended unspent transaction output (eUTXO) model, which works differently from Ethereum's account model. For beginners, its most distinctive feature is native staking. We’ve covered more about Cardano in our dedicated article.
Solana launched in 2020 as a smart-contract platform built for high throughput and low fees. SOL pays for transactions and is used for staking.
BNB was introduced by the Binance exchange in 2017. Today it is the native gas asset of BNB Smart Chain (BSC), which launched in 2020, and a utility token across the wider BNB Chain ecosystem.
XRP is the native asset of the XRP Ledger (XRPL), which went live in 2012. All 100 billion XRP were created at launch, and in 2012 the ledger's creators gave 80 billion XRP to the company now called Ripple.
Chainlink launched its LINK token in 2017 and its mainnet in 2019. It runs decentralized oracle infrastructure. Oracles supply blockchain apps with external data, such as prices, that smart contracts cannot fetch on their own. LINK is used to pay for some Chainlink services and for staking.
Tether (USDT) launched in 2014 as a stablecoin pegged to the US dollar. According to Tether's terms, each token is backed by reserves of cash, cash equivalents, and other assets, which may include loans to Tether's affiliates.
Network | Token standard | Fee token | Address format | Listed by Tether for USD₮ |
|---|---|---|---|---|
Ethereum | ERC-20 | ETH | Starts with 0x | Yes |
Tron | TRC-20 | TRX | Starts with T | Yes |
Solana | SPL | SOL | Base58 string, no fixed prefix | Yes |
TON | Jetton | TON | Usually starts with EQ or UQ | Yes |
Avalanche C-Chain | ERC-20 | AVAX | Starts with 0x | Yes |
BNB Smart Chain | BEP-20 | BNB | Starts with 0x | No (listed for XAU₮ only) |

Before buying or swapping crypto for the first time, check these five things:
✅ Define what you want to do with it
Different assets serve different purposes. Bitcoin can be used for payments and holding value, while Ethereum, Solana, and Cardano support apps and smart contracts. USDT is designed to track the U.S. dollar.
✅ Check the network
Some assets, including USDT and LINK, are available on multiple networks. Make sure the asset and network you need are supported by your wallet, exchange, and jurisdiction.
✅ Check the network fee
The asset you're sending may not be the token used to pay the network fee. For example, sending USDT on Tron requires TRX, while sending LINK on Ethereum requires ETH. Make sure you have enough of the required fee token before making a transfer.
✅ Check for extra recipient details
Some networks and receiving services require additional information alongside the wallet address. XRP deposits to exchanges, for example, may require a destination tag. Check the recipient's instructions before sending.
✅ Consider the asset's risks
Most cryptocurrencies can experience significant price movements. BTC, ETH, ADA, SOL, BNB, XRP, and LINK are not designed to maintain a fixed value. USDT is designed to track the U.S. dollar, but it still carries issuer, reserve, network, and regulatory risks.
SwapSpace has been operating since 2019 as a non-custodial crypto exchange aggregator. It compares offers from multiple exchange providers, letting you choose the available rate that works best for you. You can check user reviews of SwapSpace’s crypto providers before making your choice and also read feedback on Trustpilot.
Here’s a quick guide to swapping your first crypto on SwapSpace:
Eligible crypto-to-crypto swaps require no registration, although some providers may request additional verification. Find a step-by-step guide to exchanging or buying crypto on SwapSpace here.
Compare & SwapThere is no single answer, because the right asset depends on what you want to do. Assets with long mainnet histories and documented rules, such as Bitcoin, Ethereum, and XRP, are easier to learn on. Stablecoins like USDT track the US dollar but carry issuer risk. Compare how each one works before choosing.
Bitcoin has fewer moving parts: a narrow focus on payments and saving, a fixed cap of 21 million BTC, and fees paid in BTC. Ethereum runs apps and tokens, and every action costs gas paid in ETH. Learning Bitcoin's transfer basics first makes Ethereum's gas model easier to follow later.
No. USDT's dollar peg depends on Tether's reserves and its ability to redeem tokens, and Tether can freeze tokens under its terms. Licensed EU platforms no longer offer USDT to EEA clients. Sending USDT on the wrong network can also cause delays or losses. Treat it as a lower-volatility asset, not a risk-free one.
No. Most coins divide into very small units. One bitcoin equals 100,000,000 satoshis, one SOL equals 1,000,000,000 lamports, and one XRP equals 1,000,000 drops. Exchange providers set their own minimum amounts, so check the minimum and the network fee before a small first swap.
Tether lists USD₮ on 13 supported networks (as of September 2026), and each version has its own address format, fees, and requirements. If the sender uses Tron and the recipient expects Ethereum, the transfer may not arrive where intended. Always confirm the exact network name, such as TRC-20 or ERC-20, on both sides.
You can purchase crypto with fiat currencies such as USD, EUR, and 90+ other currencies, depending on your jurisdiction and the payment options available. SwapSpace lets you compare available fiat-to-crypto offers without creating an account. KYC requirements depend on the selected fiat provider and may apply when you proceed with the purchase. The exact payment methods, supported fiat currencies, and verification requirements are shown for each available offer before you complete the transaction.
A destination tag is a number that identifies the recipient behind a shared address, such as an exchange's XRP deposit address. The exchange uses it to credit the right account. If a platform shows a tag, include it with the address. A missing tag can delay a deposit or require a support request.
Never share your seed phrase, and ignore unsolicited messages from accounts posing as support staff. Before sending, compare the full recipient address, not just the first and last characters, because scammers create lookalike addresses. Use only official websites and apps, and send a small test amount before larger transfers. Our safety guide might also help you.
