An asset class that your author has been researching substantially is cryptocurrency. Bitcoin and the other alt coins, appear to be like very few other investment assets and so far moves in very different ways to almost every other asset. While it is very volatile and high risk and has quite a learning curve, it might be useful for some investors to understand and add to their portfolio.
Define and write down the conditions under which you'll enter a position. "Buy during uptrend" isn't specific enough. Something like this is much more specific and also testable: "Buy when price breaks above the upper trendline of a triangle pattern, where the triangle was preceded by an uptrend (at least one higher swing high and higher swing low before the triangle formed) on the two-minute chart in the first two hours of the trading day."
Those exchanges allow the purchase of cryptocurrency either via a card payment, or via a wire transfer / SEPA deposit from your bank account. They will also require some sort of identification because they are bound by financial laws related to customer due diligence and AML (anti money laundering) legislation. You may be asked to provide identification information such as an ID card, a passport or a proof of address. Note that some sites have different thresholds to buy cryptocurrency or withdraw fiat currency to your bank account based on the level of identification info you have provided. If you are into this seriously, make sure to provide the info necessary to the level you want to reach in time, not at the last minute when you want to liquidate your positions (or said differently, when you want to cash out).
Many online brokerages do not limit their customers to just online stock trading. Full-service brokerages offer banking services including checking accounts, savings accounts, credit cards, mortgages, and more with deposits of up to $250,000 backed by the FDIC. Bank of America (Merrill Edge) and Chase (Chase You Invest Trade) are two examples of banks that also offer online trading.
Crypto-only exchanges do not handle any fiat currency, they don’t work at all with « real world money ». They will however allow you to trade a very large amount of cryptocurrencies. They have « markets », where you can exchange mainstream cryptocurrencies like Bitcoin (BTC), Ethereum (ETH) or Litecoin (LTC) for other less known cryptocurrencies. They will offer similar services as advanced exchanges but you will not be able to cash out. You would have to convert the cryptocurrencies you own to a more common one (BTC, ETH or LTC for example), send it to one of the fiat to cryptocurrency exchanges, and then transfer it to your account. Alternatively, you could also just decide to pay for goods and services in cryptocurrency. Or you could also withdraw the money via Bitcoin ATMs (where you send Bitcoin to an address and get cash, just like you would on a regular ATM).

A company's stock price has nothing to do with its value. A $50 stock can be more valuable than an $800 stock because the share price means nothing on its own. The relationship of price-to-earnings and net assets is what determines if a stock is overvalued or undervalued. Companies can keep prices artificially high by never conducting a stock split, yet not have the underlying foundational support. Make no assumptions based on price alone.
This is a more advanced topic for those who want to do what is called « day trading », i.e. those who plan to buy and sell on a daily basis as their main activity. Arbitraging is the process of leveraging price differences between exchanges to make a profit, by buying cryptocurrency cheap on a given exchange and selling it for a higher price on a different exchange.

A local financial regulator or competent monetary authority or institute is assigned the task of regulating the stock market of a country. The Securities and Exchange Commission (SEC) is the regulatory body charged with overseeing the U.S. stock markets. The SEC is a federal agency that works independently of the government and political pressure. The mission of the SEC is stated as: "to protect investors, maintain fair, orderly, and efficient markets, and facilitate capital formation."

In the professional world, one of the key concepts is diversification. Harry Markowitz is a Nobel prize winning economist and one of his major discoveries was that adding new asset classes can dramatically alter the overall risk profile of a portfolio. His finding was that a portfolio that contained very low risk assets would normally benefit from lower volatility and higher returns if a higher risk asset was added. This is due to the likely lack of correlation between high and low risk asset classes.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.
