Dennis Weidner is managing director of Cryptoticker.io GmbH in Berlin and runs the editorial operation behind CryptoTicker, published since 2017 in German, English, French and Spanish. A founder and investor, he has worked with digital business models for more than twenty years. His writing focuses on the point where regulation meets what investors actually do: MiCA authorisation of trading venues, taxation and DAC8, self-custody and staking. He works from verifiable primary sources rather than price speculation — supervisory registers, vendor post-mortems, original specifications. His articles are analysis, not investment advice.
