I would be curious to know how much $$ it took to pump gamestop stock.
A bunch of investors buying a bunch of stock--on margin--in a company that doesn't have an enormous amount of stock floating would inflate the price quite nicely, and I don't doubt that's what happened. I seriously doubt the government would have any interest in pumping Gamestop stock, nor do I think Gates and Buffett feel threatened by cryptocurrency.
This stuff is really interesting, though. It'd be nice if those Reddit peeps would pump something I owned. Too bad I'm not holding any doge right now.

I understand that doge may have its use in some cases, I like it for two reasons as well, one is the fact that they got together and did community stuff YEARS before wallstreetbets did, they helped the jamaican bobsled team and sponsored them, they had an ad spot on a nascar race car, and some other stuff I can't remember now but they are definitely a fun community to be in and do good stuff, secondly of course gambling, it makes things easier and cheaper there as well.
Long story short they are good for some things, but as you may have realize I didn't list investing in there, you may not like investing into something that is consisting of good people, just because doge people are nice and you can gamble with doge doesn't mean that I would want to invest into it, I rather invest my money into bitcoin even if bitcoin is not as cheap as doge.
