Although I cannot predict the future, and therefore, cannot say for certain whether Mavin’s act, Rema, will ever be as big as Wizkid.

However, Both artists are incredibly talented, and their success is determined by a variety of factors, including their music, marketing strategies, industry support, and fan base.

Wizkid is an established artist who has been in the music industry for over a decade and has gained a massive following across Africa and the world. Rema, on the other hand, is a relatively new artist who has been active in the music industry for a shorter period of time. However, since his debut, Rema has garnered a lot of attention and has released hit songs that have topped the charts.

Rema has already made an impact in the Nigerian music industry, and his music has been well-received by fans and critics alike. With hard work, dedication, and strategic planning, there is a possibility that Rema could become as big as Wizkid or even bigger.

In conclusion, while it is impossible to predict the future success of an artist, Rema has shown a lot of potential, and his talent and hard work may lead him to great heights in the music industry.
