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
How can I check if a crypto exchange targeting expats in Portugal is CMVM-authorised?
Search the platform directly at cmvm.pt rather than trusting claims made in the exchange's own marketing materials. If it doesn't appear on CMVM's list of authorised or warned entities, treat any authorisation claim as unverified.
Why do scammers specifically target NHR residents in Portugal with crypto pitches?
Foreign residents on the NHR scheme are often less familiar with Portuguese financial regulations and may be actively seeking tax-efficient investments, making them more receptive. Always verify tax claims with an independent adviser, not the platform selling the investment.
I can't withdraw my EUR profits from a Portuguese crypto platform — what does that mean?
This is a common pattern where a fraudulent platform shows fake gains to encourage deposits, then blocks withdrawal using invented compliance fees. Stop depositing further funds and report the platform to CMVM.
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.
