European banks are discreetly re-entering the cryptocurrency market, according to Ricardo Martins, CEO of Bison Digital. This cautious return is attributed to regulatory frameworks such as MiCA, which are enhancing institutional confidence. Martins noted that Portugal's tax regime, which imposes a 0% tax on crypto held for over a year and 28% for less than a year, is fostering long-term investment. Institutional interest is predominantly directed towards Bitcoin, which accounts for over half of client interest, and regulated stablecoins like USDC. Compliance remains a key factor in rebuilding trust within the sector, as banks navigate the evolving regulatory landscape.
