Gabriel Mas

Writes the step-by-step version of the things most guides skip over.

What Gabriel Mas covers here

Everything published on The Coin Workbook is written by one person, and the scope is deliberately narrow: onramp, offramp, swap, corporate wallet, custody, acquiring, stablecoin payments, bitcoin payments, otc, licensing, cards, industries, exchange. Articles stay inside it rather than chasing whatever is trending.

How the writing is checked

Figures carry the date they were taken. Claims that can be verified link to a primary source rather than to another article summarising it. Where something is genuinely uncertain, the article says so instead of rounding the uncertainty away.

Corrections are published with a note saying what changed and when. If you find an error, the contact page is the fastest route.
