Crypto 101: learn crypto in plain English

A calm, UK-focused learning centre for complete beginners. No jargon, no hype, and no financial advice — just clear explanations to help you understand crypto, and the risks, before you decide anything.

Before you buy crypto

A quick checklist to run through first.

  • You are only using money you can afford to lose.
  • You understand crypto is not protected like savings (no FSCS or Ombudsman).
  • You have checked the platform on the FCA Register.
  • You have checked the FCA Warning List.
  • You know the current fees, from the provider’s own site.
  • You have turned on two-factor authentication.
  • You understand prices can fall sharply and quickly.
  • You will never share your wallet recovery phrase.

Common beginner mistakes

The pitfalls that catch people out most often.

  • Investing more than you can afford to lose.
  • Trusting “guaranteed returns” or tips from social media and messaging apps.
  • Sharing a recovery phrase, or letting someone remote-control your device.
  • Assuming crypto is protected in the same way as a bank account.
  • Rushing in because of fear of missing out.
  • Not checking whether an app, website or firm is genuine.
