Your responses to the actions being taken with this shell suggest that you might have just heard of shell stocks a bit earlier today, which is fine. You should read the informative responses and look into a bit of the history of shells and prior action that they have seen to gain a better understanding of why they are of great interest to penny traders.
Very many of the largest running penny stocks of all time have started as shells. In fact the largest running penny stock ever in a 6 month period was also a shell much like this one. The argument of no one will buy this because it is a shell when nearly half of the biggest penny runners in the past couple of decades began as shells, doesn't hold much weight.
In the case of this particular shell, there is heightened interest because it has already been made clear that PLPL was cleaned up specifically for major corporate actions to take place, such as reverse mergers or LOI's. On top of that they aim to have thos shell audited which would make it an even better candidate for a larger private company to merge into.
Shell investing otherwise can usually be far more hit or miss due to not preemptively already being aware of the stated future plans for a shell. We just don't know what company may be merged in but we are aware of the intent in advance, making it a more attractive investment prospect.
