No one knows. I recommend putting whatever you can afford to lose into it. Whatever seems "wise" within the scope of "it might be worthless". Do I think there is much chance of it being worthless? Not even a little bit. The intrinsic value of the stock is probably more than its cost right now. This is the value having nothing to do with the short squeeze. The GameStop company is under new ownership and will likely completely dominate the gaming market for the medium term future (at least). Not just in game sales, but all sectors of the gaming market.

In addition to intrinsic value, it has more potential to be the best investment of any of our life times than anything I've ever seen. Will that happen? I have no idea, but it might. We shall see.
