"Hey wouldn't it be funny if you gave me your life savings? That would be so funny right?" That's why its gross.
Yes, this hyperinflationary coin or pre-mined one means that selling it is just a roundabout way of getting people to give you money "for the meme"
Imagine if I printed out a bunch of images and said "Wouldn't it be so funny if you dumped your life savings into buying these?" Its actually not funny at all. Actual gambling has rules to it at least. These are just grifts. Gambling does not describe them.
