SALT would be unlikely since it was just recommended as a short term trade by PBC a few weeks ago, but it is possible.

A more likely pick would be SLR, since it was the one he strongly hinted at for last month. There are several 4chan and reddit posts illustrating all the points as to why he was most likely considering this. It was delayed because people pumped it before he could release it to his subscribers. Since it is quite a bit down now, it would theoretically be a good time for him to release it, as long as it isn't pumped again prior to the next release (Dec 21).
