If you haven't already sold your ALTs simply hold if your project is decent. If the project has no future sell and buy into a decent project. This is all you can do to recover your loss without putting in more money. It will probably take a couple of years to recover your loss!
Some ALTs will never recover from this crash!
It is an ugly situation!
It's quite difficult to hold assets that only bring you losses and headaches. Personally I would close positions on those projects in which there is no confidence. Why risk even such a small amount?
