Claiming to be the first Polish warehouse to store noble metals, it offered its clients controversial investments in gold and other bullion.

Since December 2009 the Polish Financial Supervision Authority (Komisja Nadzoru Finansowego, KNF) had been warning that Amber Gold did not have its consent to perform banking activities and accept cash contributions in order to burden them with risk.

A number of charges had been brought against Plichta, including attestations of untruth, failure to submit the company's financial statements, performing unregistered currency exchange and bank activities.

Disciplinary proceedings were also initiated against the prosecutor who accepted Plichta's request for voluntary submission to penalty in earlier cases, though they were later discontinued.

In 2013, the National Bank of Poland's Financial Stability Committee published a report in which it noted that the extortion of money from over 11,000 people committed by Amber Gold was possible, among other things, due to omissions on the part of public institutions, pointing mainly to the Regional Prosecutor's Office of Gdańsk-Wrzeszcz, the Office of Competition and Customer Protection, the Central Investigation Bureau, the Internal Security Agency, and some banks that cooperated with the company.
