Krstić was born in Latovo, near Makedonski Brod in the Poreče region, at the time part of the Sanjak of Monastir, Ottoman Empire (present-day North Macedonia).

After the war, the Serbian military government sent armament and aid to rebels in Kosovo and Macedonia.

[4] Many of those bands, privately funded and aided by the government, were established in Serbia and crossed into Ottoman territory.

[4] In that way, Micko Krstić formed a rebel band in 1879 in Niš, with the help of Nikola Rašić and the military government in Vranje.

[8] The Brsjak Revolt, and the preceding ones in Kumanovo, Kriva Palanka and Kratovo, had all a Serbian character, planned in the Serbian cause, thus, the unsuccessful outcome resulted in persecution of Serbs in the Macedonia region, with an increased Bulgarization of the region's Christian Slavic populace.

[13] Finally, in 1901, the Serbian consulate managed to have him released, though he was under house arrest in Bitola, and was obliged to contact the town government every day.

[15] Meanwhile, the first Serbian guerilla bands were formed through self-organizing of Serb villages in Poreče, Kumanovo and Kratovo provinces, which, along Veles, were exposed the most to Bulgarian violence.

[15] Krstić's escape, on April 4, 1904, was organized by Savatije Milošević, of the Bitola Consulate, Jovan Ćirković-Ćifa, a secretary of Metropolitan Polikarp, Lazar Kujundžić, manager of schools in Kičevo, and Marko Cerić.

[15] The Bulgarian bands were resting in a ravine following clashes with the Ottoman army at Movnatac, located at the entrance of Poreče.

[15] The Serbian Chetniks, numbering c. 40 fighters, silently surrounded them, and with a sudden raid, destroyed the five-times greater enemy.
