About Mikael Olsson
Mikael Olsson is co-founder of Preciobitcoin alongside Sebastian Olsson. Since 2017, he has been researching Bitcoin, cryptocurrencies, and the European digital asset ecosystem, with a special interest in taxation and how the MiCA framework affects Spanish users.
At Preciobitcoin, he writes and reviews guides on how to declare cryptocurrencies to the tax authorities, analysis of MiCA-licensed exchanges, hardware wallet reviews, and educational content for those new to Bitcoin.
His editorial approach is straightforward: clear, verifiable, and independent information, free from conflicts of interest with exchanges or crypto projects.
