After graduating from high school, he joined various university programs but he had to quit for economic reasons.

Following his military service, he released Kral Çıplak in February 2001, Bir Erkeğin Günlüğü in October 2002, Aç Pencereni in September 2004, and Annemin Türküleri in 2005.

[4] He later said he would not attend the gala due to the criticism aimed at the Turkish government in the entry penned by Elif Shafak.

[6] In August 1997, he was arrested and imprisoned for a bounced check for 3 million liras from ten years ago.

[7] While in prison, he cut his long hair and sent it to Gülnar to protest the nuclear power plant project.

After his military service, he released his albums “Kral Çıplak” in February 2001, “Bir Erkekeğin Günlüğü” in October 2002, “Aç Pencereni” in September 2004 and “Annemin Türküleri” in April 2005.

Haluk Levent, who is one of the most frequently performing artists in Turkey, did not receive any money from most of these concerts and donated the proceeds to patients who need.

[9] Following the earthquake in February 2023, his NGO Ahbap assisted the affected which made him very popular among the Turkish society.

Critics accused the project’s founder of failing to address concerns[12] and claimed Levent’s public endorsement had encouraged participation.

[13] Levent later denied any intention to mislead investors, emphasizing he was not involved in managing Nigella World’s day-to-day operations.

In a 2024 LinkedIn post, Nigella World announced the launch of the “Nigella Blockchain Academy,” crediting Levent’s contributions and outlining plans to expand blockchain applications to finance, healthcare, and supply chain management.

[15] Additionally, Levent collaborated with a local crypto exchange on the “HALUK” token, which was promoted as a charitable endeavor.

[16][17] While these ventures initially attracted public interest, they also drew criticism regarding transparency and the volatility of new digital assets.
