Bitcoin is the opposite of a pyramid scheme from the point of view of Bitcoin miners. The Bitcoin protocol is designed like a cannibalistic arms race. Every additional miner prompts the protocol to increase the difficulty of mining. From a social point of view, Bitcoin is a pure market. The price of Bitcoins fluctuates based on market supply, demand, and perceived value.
The problem is that a lot of newbies think that bitcoin is just a pyramid scheme because other users need to buy in order to see the price increasing, but it just works like anything else. Like gold, silver, or any other shit asset.
