Bitcoin has come a long way since its early days. In 2025, it's no longer just for tech-savvy enthusiasts or millionaire investors. With greater accessibility, user-friendly tools, and a growing number of secure wallets, you can start investing in Bitcoin today—even with as little as $100.
Whether you're a beginner exploring crypto for the first time or someone looking to diversify a portfolio, this guide will walk you through how to get started, step-by-step. Plus, we’ll help you choose the best bitcoin wallet to protect your investment.
Why Invest in Bitcoin?
Bitcoin is the world’s first decentralized digital currency, designed to operate without the need for intermediaries like banks. Its limited supply of 21 million coins makes it a deflationary asset—some even call it digital gold.
In recent years, institutional adoption, global inflation, and growing distrust in traditional finance have propelled Bitcoin into the spotlight as a reliable store of value. Starting small can help you get comfortable with how Bitcoin works while participating in its long-term growth potential.
Step 1: Set a Budget — Even $100 Is Enough
Contrary to what some might believe, you don’t need to buy a whole Bitcoin to get started. Bitcoin is divisible into units as small as 0.00000001 BTC (called a “satoshi”), so even $100 can buy a small portion.
Investing with a smaller amount is smart for beginners because it lets you learn the ropes without taking on significant risk.
Step 2: Choose a Reliable Exchange
To purchase Bitcoin, you’ll first need to register with a cryptocurrency exchange. These platforms let you convert fiat (like USD or EUR) into Bitcoin. Some of the most trusted exchanges in 2025 include:
Coinbase – Ideal for beginners, with a simple interface
Binance – Offers low trading fees and advanced tools
Kraken – Known for its strong security and wide crypto selection
Bitstamp – One of the oldest and most trusted in the industry
Look for platforms that are regulated in your country, offer strong security measures, and provide transparent fees.
Step 3: Secure Your Bitcoin with the Best Wallet
Once you've purchased Bitcoin, don’t leave it on the exchange. Keeping your BTC in an exchange wallet means you're trusting them to safeguard your assets—a potential risk. Instead, transfer your funds to a bitcoin wallet where you hold the private keys.
What Makes the Best Bitcoin Wallet?
Security: Your wallet should encrypt your private keys and support backup options
User Control: Choose a non-custodial wallet where you control your funds
Compatibility: The wallet should support the Bitcoin network and possibly others
Backup & Recovery: Ensure you can recover your wallet using a seed phrase
Mobile/Desktop Access: Depending on your preference, choose a platform that suits your daily use
