He began editing the
Anatolikos Astēr in 1862. In 1864, he left the first publication and began editing
Heptalophos; he received ownership of it in 1865 and renamed it
Nea Eptalofos. During periods when
Kōnstantinoupolis was not in operation, Nicolaides edited
Thrakē ("
Thrace"; August 1870 – 1880) and
Avgi ("Aurora"; 6 July 1880 – 10 July 1884). He edited a French-language collection of Ottoman law,
Législation ottomane, that was published by
Gregory Aristarchis. He also edited the Greek version of the
Düstur, Оθωμανικοί Κώδηκες ("Othōmanikoi kōdēkes", meaning "Ottoman Codes", with
Demotic Greek using "Οθωμανικοί κώδικες"), its first non-Turkish version. These two publications enriched him financially, After the Ottoman government received the Greek version, it made him a third-class civil servant. The Bulgarian copies of the
Dustür circulating stated that they were written by Christo S. Arnaudov (; Post-1945 spelling: Христо С. Арнаудов), who published it. Johann Straus concluded that the Bulgarian version probably originated from Nicolaides's Greek version due to "striking similarities" between the two, Gedeon stated that Nicolaides obtained 5,000 gold francs from the Ambassador of Russia to the Ottoman Empire, Ignatieff, to fund this publication, and that he did not give much of this away to other parties. According to Gedeon,
Theodoros Kasapis wrote in
Diogenis that the Russian ambassador had bribed Nicolaides. Ultimately, in 1889, he established an
Ottoman Turkish newspaper,
Servet. For a period, his main printing facility was at Millet Han in
Galata. He applied to move to a new facility twice, to Financılar Yokușu in 1899, approved but not completed, and then to Lloyd Han in 1902, also approved. The move was completed by 1903. Because Nicolaidis tried to save his newspapers no matter what it took, he sold his possessions and lost his wealth. ==Life and death==
