Useless effort?

[Iwantosavemyorchids]

This orchid was give to me as gift. The person didn’t check the roots only the flower. Long story short it came with rot root/ stem. I tried to stop the infection but it lost two leafs and all roots in the process and I’m not sure if it still has something that we could call a stem.

So I felt sorry for it and as the infection stopped, I started to leave it with moss under the plant and she is on some rocks (avoiding directly water). It is starting to show a new leaf and absolutely no root. Do you guys think it still has a chance or it is just a poor effort and she will eventually pass for the plants heaven?
