Who buys this garbage, and why?
I think it's split between people who want to play or invest on Just-Dice.com, and people who want to speculate on the price.
Honestly, you have zero real-world adoption, you have some of the biggest snakes on the forum constantly shilling for it, trying to trick noobs into buying it like it were some sort of haphazard ponzi scheme, and the biggest bump you got is when Stephen Colbert made fun of it as an example of how crypto kids will buy anything.
I don't see anyone shilling for it. Nobody is promising any kind of return on investment, so it's clearly not a Ponzi scheme. You're thinking of John Oliver's hit piece I think, not Cobert's, and I didn't notice any "bump" as a result of his bit.
Oooh you can stake it and get free Clams.... but only if you buy a shitload first.

How retarded are people becoming?
This coin is the essence of a Ponzi scheme, people.
You can stake with any amount of CLAMs. The percentage return will be the same on average. The return is low, and should correspond with a per-unit decrease in price as the supply increases. Nobody is advertising staking CLAM as a way of getting rich, and I haven't seen any Ponzi schemes based on CLAM.
Read the words in the image you linked. Notice how none of them apply to CLAM in the slightest. There's no promised returns on investments. There's no "schemer" to collapse the "scheme". Etc.
Give me one reason to buy this coin. Other than because I can buy it on Cryptopia and sell it on Polo for a tidy 5% arb profit.
Do your own research. Buy it if you want to buy it. Don't if you don't. Nobody is trying to trick you into buying it.
