"Muntaha" (مُنتَہیٰ, with a damma on م, a sukoon on ن, a fatha on ت, and a vertical fatha on ہ) means "the furthest limit of something, the end, or the conclusion". Given this meaning, the name serves no positive purpose. It would therefore be better to choose a name that carries a meaningful and worthwhile significance.
Allah the Almighty knows best.
