How to save my orchid?

[starwave]

This is my first orchid. Liu’s cute, bought from a show around 2.5 years ago.
At the beginning it grew very well in moss. Later I did something wrong and root started to rot. I tried to re-pot a few times and didn’t make it better.
Two weeks ago, I hanged it in my restroom without any medium, spray water a few times every day. Just wanted to see if I could stop the rot.
That space is bright without direct sunshine. Humidiy is 45-55%.
After two weeks, I saw two new roots coming out, one old root having green tip became longer. However, two old leaves fell. Those two leaves had yellow spots before I hanged it.
My question is that: should I pot it now? Or keeps hanging?
I am afraid it is too dry. After water spray, roots became white very quickly. And two leaves falling makes me worried.
On the other hand, new roots coming out seems to be good.
Any suggestion is welcome!

Pictures show two weeks ago and now.
