Pump and dump schemes: In a pump and dump scheme, a group of individuals artificially inflate the price of a cryptocurrency through coordinated buying, and then sell off their holdings once the price has reached a peak.

To protect yourself from these and other scams, it is important to do your due diligence and research any investment opportunity before committing any money. This includes verifying the legitimacy of the company or individual offering the investment, and being wary of unrealistic promises of high returns with low risk.

Chapter 10: Cryptocurrency Mining

Cryptocurrency mining is the process of verifying and adding transactions to the blockchain, and is an essential part of how cryptocurrencies work. Miners use powerful computers to solve complex mathematical problems, and are rewarded with a small amount of the cryptocurrency they are mining for each successful verification.

There are several different types of cryptocurrency mining, including proof-of-work, proof-of-stake, and delegated proof-of-stake.

Proof-of-work: In proof-of-work mining, miners compete to solve complex mathematical problems in order to verify transactions and add them to the blockchain. The first miner to solve the problem is rewarded with a small amount of the cryptocurrency being mined.
