By your definition all stocks are ponzi schemes. Stocks are basically 'premined' by total shares outstanding. The float is then sold to investors. The rest is locked up to either insiders or the company treasury. The nice thing about cryptocurrencies is that they generally don't get diluted whereas stocks can issue more shares and dilute their investors if they so choose. Also cryptocurrencies don't have earnings estimates to miss. If your stock misses its earnings estimate then it generally gets whammed.
huge difference with stocks.
they are regulated. the gov can pull your corporate charter at any time and kill the company. huge huge difference than crypto where any fly by night can fork a project, change a few lines of code, and have established miners jump on it for the next pump and dump.
also you are incorrect that cryptos cant get diluted. a coin can offer an infinite amount 'colored' versions of itself. or tokens based on the coin (like ethereum erc20). google stock can only be google stock. alt coin can be alt coin-red coin-blue etc edition.
there is no accountability with crypto alts coins (worse with ICOs). you can operate in obscurity and cover your tracks the whole time. not so with a stock company.
You, my friend, have not spent enough time in the pink sheets! As a general rule of thumb, they are much worse and much more apt to be shell companies and have fake assets, etc than the cryptos. With cryptos, especially the ones that are not premined, you still have the miners to satisfy and everyone starts out somewhat evenly. So even in a pump situation if you buy low and sell high you can still end up okay. I am not saying there aren't crypto scams, I am not saying they don't get diluted at all, but most coins have a hard cap. There are some aspects of commoditization with cryptos, but that is where PR can be used to set coins apart from the mass market.
Also I would say that most coins that are designed to pump have some burn feature incorporated. Two interesting ones to note that I am watching but am not invested in are Slim coin (SLM) and Obits token. Slim coin works with PoW, PoS and PoB, proof of burn where in order to mine some coins can be burned in order to mint more coins in the future. They are only on one exchange and that exchange is having problems. They are looking to relist somewhere else. The technology is interesting imo. OBITS is a token that is listed on its own exchange. The owner of the exchange then acts to buy back and burn tokens each month, decreasing the outstanding supply. It is one token where the supply is actually decreasing. I AM NOT RECOMMENDING THESE. I AM JUST WATCHING THEM FOR FUN AND INTEREST. I enjoy the market dynamics of these cryptocurrencies.
