History has shown that there are a lot of "greedy", but dumb people. A fantastic example comes to mind: In the Netherlands we have a saying "to sell fried air" (Gebakken lucht verkopen) to explain someone selling bullshit.

Yet, in the "dotcom"-hype, there was a Dutch company selling shares for their startup, "f/ried air" and people got in line to buy these shares.

There will be people buying into Dogecoin, simply because they are greedy and see profit, and choose to ignore the signs that it is a clear Pun.
