How to Buy Bitcoin (Beginner's Guide): Exchange, KYC, Storage & Tax
Bottom line: six steps, starting small
You can buy Bitcoin through a regulated cryptocurrency exchange in small amounts. The flow is: choose an exchange → verify identity (KYC) → deposit → buy → store safely → understand tax. In Japan, use an exchange registered with the Financial Services Agency (FSA). We don't recommend specific providers — compare neutrally.
Key takeaways
- Use a regulated exchange (in Japan, FSA-registered). This is the first thing to check.
- "Brokerage/instant buy" is easy but has a wider spread; an order-book "exchange" is usually cheaper.
- The real work is safe storage after you buy — don't leave large amounts on an exchange.
- If you make a profit, check the tax rules (in Japan, see the tax guide).
Step 1 — Choose an exchange
Confirm it is licensed/registered in your jurisdiction (in Japan, FSA-registered). Then compare:
- Security: two-factor authentication, cold storage, segregation of customer assets.
- Fees: trading, deposit/withdrawal, and the spread.
- Usability & support: a clear app, small-amount support, responsive help.
Step 2 — Open an account & verify (KYC)
After registering, you complete identity verification (KYC) with an ID document and usually a selfie check (eKYC). This is required by anti-money-laundering law and can't be skipped.
Step 3 — Deposit funds
Fund the account by bank transfer or card. Only use money you can afford to lose — never living expenses or borrowed money.
Step 4 — Buy (brokerage vs. order book)
| Method | Trait | Best for |
|---|---|---|
| Brokerage / instant buy | Simple; wider spread | Quick, tiny first buy |
| Order-book exchange | Trade with other users; lower cost | Keeping costs down |
Some people buy a fixed amount on a schedule (dollar-cost averaging) instead of trying to time the market — a steady, lower-stress approach.
Step 5 — Store it safely
This is the most important step. Coins left on an exchange are exposed to exchange hacks or insolvency (historically, Mt. Gox). As your holdings grow, consider self-custody with a hardware wallet (cold storage). See the safe-storage section of the what is Bitcoin guide. Scammers specifically target new buyers with fake exchanges, phishing links and impersonation — see Bitcoin scams and how to avoid them before you move funds.
Step 6 — Understand the tax
Tax treatment varies by country. In Japan, Bitcoin profits are generally miscellaneous income (comprehensive taxation), taxed together with other income. Always confirm with the official tax authority for your situation. This applies to more than just selling — in many places, spending Bitcoin directly is also treated as a taxable disposal; see how to spend Bitcoin for what that means in practice.
