I can't begin to point out your many wrong assumptions in this post,

You'll see crypto as a Ponzi if you are investing in pump and dump tokens which do not offer to solve any real world problems.

About crypto having finite number of investors, the stock market also has finite numbers of investors but has it gone down to zero ? Why has it not hit a saturation point since it's decades of existence??

There is no ceiling to how much money can pour into crypto and stock, as long as population keeps growing, production of consumer goods keeps going up and yes most importantly, the money printing machines of government keeps running... In the first place the reason behind investing is not only to build wealth but to also beat inflation which eats away at your savings....

So no... This post can't be any right... Bitcoin has a working technology behind it, so is Binance or Ethereum, you only come to this conclusion because you have bought into hypes without a product
