Crypto Scams in Portugal
Fraudulent cryptocurrency schemes targeting Portuguese investors and expats, exploiting Portugal's growing fintech profile and NHR crypto tax treatment.
Part of: Crypto Scams
Last reviewed: 1 June 2026
Portugal's historically favourable tax treatment of crypto gains and its growing tech expat community have attracted fraudulent platforms and token promoters targeting both Portuguese nationals and foreign residents. Fake exchanges claim CMVM registration, and scammers specifically pitch crypto investments as NHR tax-efficient to attract foreign residents.
CMVM has added numerous crypto platforms to its warning list, and Banco de Portugal cooperates with PJ on crypto fraud investigations. Losses range from modest individual amounts to significant sums among higher-net-worth victims.
How this scam works on Portugal
Fake crypto exchanges advertise in Portuguese social media using celebrity or influencer endorsements. They accept EUR via MB WAY or SEPA, display impressive dashboards, then block withdrawal with invented CMVM compliance fees.
Scammers specifically pitch crypto investments as NHR tax-exempt to foreign residents, exploiting uncertainty about Portuguese tax rules to seem credible.
Phishing campaigns impersonate legitimate Portuguese fintech services or international exchanges localised for Portugal, harvesting login credentials via lookalike login pages.

Frequently asked questions
Is crypto income really tax-free in Portugal for NHR residents?
Portuguese crypto tax rules have evolved; specific treatment depends on circumstances and may have changed. Always consult a licensed Portuguese tax adviser rather than relying on information from an investment promoter.
