The more people who buy in, the less value something has for those who can only afford a small amount.

Isn't this true for everything that's scarce and valued by supply vs demand? Also, a lot of this value increase is due to the true dollar inflation, people are less willing to take something that drops in value in exchange for something that will hold or go up in value over time.

Whales ALWAYS benefit more than anyone else.

Whales are in every market, they buy low and sell high, so of course they're gonna benefit from all the idiots that does the opposite.

I've yet to see people advertise in the same way for hand and power tools.

Agreed, it's almost like people haven't figured out why they would need such tools, especially hand tools and mechanical stuff in general. We shouldn't rely too much on electricity as long as we can't generate it easily.

If you find a hill full of gold, you don't go off and tell people to come and get it.

This is true for crypto too, honestly, when was the last time you saw ads for crypto mining? Sure hardware manufacturers may advertise, but that's no stranger than CAT, Volvo or Atlas Copco advertise their machines.
