TL;DR: For most beginners, Bitcoin and Ethereum are the safest starting points. They have the longest track records, the deepest liquidity, and the widest institutional support. Altcoins and memecoins carry significantly higher risk.
Why "Which Coin Should I Buy?" Is the Wrong First Question
Most people new to crypto immediately ask "which coin should I buy?" — but a better first question is "how much am I willing to lose?" Crypto is a highly volatile asset class. Before choosing a coin, set a budget you're comfortable with regardless of outcome.
With that in mind, here's how to think about the options.
Bitcoin: Digital Gold
Bitcoin (BTC) is the original cryptocurrency and still the most widely held. Its key properties:
- Fixed supply — only 21 million BTC will ever exist
- Deep liquidity — you can buy or sell large amounts without moving the price significantly
- Institutional backing — spot Bitcoin ETFs from BlackRock, Fidelity, and others launched in 2024, bringing hundreds of billions in managed assets
- 15+ year track record — Bitcoin has survived multiple crashes and always recovered to new highs
Bitcoin won't 10x overnight, but it's the closest thing crypto has to a "blue chip" asset.
Ethereum: The Smart Contract Platform
Ethereum (ETH) is the second-largest cryptocurrency and the backbone of decentralised finance (DeFi), NFTs, and most blockchain applications. Why it matters for beginners:
- It's the native currency of a massive, active ecosystem
- It has staking yields — you can earn ~3–5% annually by staking ETH
- It's liquid and available on every major exchange
ETH is more volatile than BTC but also has more potential upside if the Ethereum ecosystem continues growing.
What About Altcoins?
Altcoins — everything other than Bitcoin — range from solid projects with real utility (Solana, Chainlink, Avalanche) to speculative bets on unproven technology. The risk profile is significantly higher:
- Lower liquidity — harder to exit at a fair price during a crash
- Higher volatility — 50–80% drops are common even for top-20 coins
- Project risk — teams can disappear, code can have bugs, hype can evaporate
If you want exposure to altcoins, a common approach is to keep them as a small percentage (10–20%) of your total crypto allocation and stick to projects in the top 20 by market cap.
Should Beginners Buy Memecoins?
Memecoins (Dogecoin, Shiba Inu, and hundreds of others) are driven almost entirely by social media hype. Some people have made enormous gains. Many more have lost most of their investment.
The honest answer: memecoins are closer to gambling than investing. If you want to participate, treat any money you put in as money you've already lost. Use only a tiny amount you're comfortable watching go to zero.
How Much Should You Invest?
A widely cited framework for beginners:
- Only invest money you don't need for at least 3–5 years
- Start with an amount that won't cause you to panic-sell if it drops 50%
- Consider dollar-cost averaging (DCA) — investing a fixed amount weekly or monthly rather than all at once
There's no minimum. Most exchanges let you start with as little as €10–20.
The Simplest Beginner Portfolio
If you want to keep it simple:
- 70% Bitcoin — the most established, least volatile option
- 30% Ethereum — exposure to the smart contract ecosystem
This portfolio has outperformed most altcoin strategies over 3+ year time horizons while carrying less risk than picking individual projects.
Key Takeaways
- Bitcoin and Ethereum are the safest starting points for beginners
- Altcoins carry higher risk — only invest in top projects with real utility
- Memecoins are speculative — treat any money there as disposable
- Start small, invest regularly, and don't invest more than you can afford to lose
