That's fine, I don't think you have any evidence for your position though. You could easily make the opposite argument that Doge is basically a marketing campaign for BTC and will bring in more investment dollars than it sucks away. It's not zero sum.

Why would BTC need a marketing campaign? Isn’t it a value store? Or was it a currency? Or is it perhaps a bubble of nothingness that actually would need a marketing campaign?

I have put about $1000 into various cryptos as a hedge, but I fully expect to lose it all and the day can’t come soon enough.

Saying something acts as a marketing campaign != saying it needs a marketing campaign, I'm not sure how you made that leap..

My point is that Doge doesn't necessarily take cash inflows away from BTC, describing a possible mechanism for the opposite phenomenon, not that anything needs a marketing campaign.
