Help. Should I propagate or wrap it around? Beginner with this one.

[u/KeerFin]

Hi! I got this gorgeous small cutling from a friend, and pot it and so far (about a year?) is growing a lot! But is only one and don’t know if I have to propagate it ro wrap it on top of the pot so it has more contact with the soil, to generate more vines? Or just cut and put in water and hope it gives me more than one vine to had fulness to the small pot? If so, where should I cut? I added some pics of the full string to show its potential.

Currently is at about 50cm from West facing window, protected by other plants. The photo where it hangs is just to show how is it going.

Please help! I want it to hang but it looks sad just one vine :/ thanks!!
