The problem with MOND is that it's just math. It doesn't explain anything in terms of cause and effect because it doesn't have a physical basis. The problem with the cold dark matter model is that it posits a massive, slow moving particle. A slow massive particle would be attracted to other bodies and to other dark matter particles and form clumps in orbit. This is not observed.

There's a better hypothesis that not only explains the cause of gravity, but also posits that dark matter consists of positive and negative electric photons that continually radiates from all massive particles. Lots of it. They can't be detected electrically because their net effect is neutral but they still cause gravity.
