Do · Guides for wallets, exchanges, security and tax

Do

Practical guides, step by step. Where the law or the tax rules matter, a guide is written for one country and reviewed for it, and it shows when it was last reviewed and when the next review is due.

No account needed. Dated and reviewed. Never a personal tax calculation.

There are no guides for Switzerland yet. The countries below have guides.

No country has guides of its own yet.

Families of guides

Start with questions, not with product names.

Who holds the keys? Can anyone block the balance? What happens if the provider disappears, or the phone is lost? Each family answers in order, one guide at a time.

Countries

The rules where you live, in one place.

Each country hub brings together the guides, the tax guide, the licensing register, the cash rules and a short Country Money Story. Guides are localised by someone who knows the country, not translated.

Country hubs: what we have for one country on one page

How we know

Every guide names its date and its limits.
