I am not sure there is anything anyone here can do or tell you, as your issue is solely with Mercan. When you signed on to them, this was always a risk that came with it.
I don’t know that you need to transfer your investment. Technically your investment is still intact, even if the value has gone to $1 it should not impact your GV. Mercan also offers a buyback, if they will honor that.
In the end, you are probably overthinking the situation. Mercan is a large company and may make it right in the end.
