Bečić was born in Cetinje, Montenegrin Old Royal Capital, at that time part of the Socialist Republic of Montenegro of SFR Yugoslavia.

[2] He led the Socialist People's Party electoral list in the Podgorica local election of May 2014 under the slogan "youth, wisdom and courage".

[10] On 5 October 2020, Bečić, along with the European Union Ambassador to Montenegro Oriana Christina Popa opened the new War Crimes Documentation Centre in the capital Podgorica, stressing that the country must face up to its wartime past.

[13] Bečić had repeatedly denied these allegations,[14] calling it a coordinated smear campaign jointly conducted by parts of the DF and the ruling DPS.

[15] On 25 July 2024, Bečić, along with parliamentary speaker Andrija Mandić and MP Milan Knežević were declared persona non grata by Croatia following the passage of a resolution in the Parliament of Montenegro recognising a genocide in the Jasenovac concentration camp committed by the pro-Axis Independent State of Croatia during World War II.
