Stock brokers are people or firms licensed to buy and sell stocks and other securities via the stock market exchanges. Back in the day, the only way for individuals to invest directly in stocks was to hire stock brokers to place trades on their behalf. But what was once a clunky, costly transaction conducted via landline telephones now takes place online in seconds, for a fraction of what full-service brokers used to charge for the service. Today, most investors place their trades through an online brokerage account. (A little lost? Check out our explainers on brokerage accounts and buying stocks.)

When you buy some cryptocurrency, the money will be withdrawn from your bank account or card and you will be credited in your exchange in a sum matching the cryptocurrency you have purchased. Each exchange may allow you to trade for one or more cryptocurrencies. Each cryptocurrency on the exchange will have its own wallet. You can store your cryptocurrency on an exchange but it’s not a recommended practice. I will cover this in a section called Wallets.


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.
To buy cryptocurrency using what is called « fiat currency » (i.e. Euros, Dollars, Yen, whatever is your local currency), you will need to sign up to an exchange. There are two kinds of exchanges: fiat to cryptocurrency exchanges and cryptocurrency only exchanges. Obviously to get started you will need to go into an exchange that allows the purchase (and selling) of cryptocurrency against fiat currency, such as Coinbase, Kraken, GDAX etc. (note that some instant access exchanges – see below- also allow instant purchase with cash).

Blockchain Ventures: Amid rising popularity of blockchains, many crypto exchanges have emerged. Such exchanges are venues for trading cryptocurrencies and derivatives associated with that asset class. Though their popularity remains limited, they pose a threat to the traditional stock market model by automating a bulk of the work done by various stock market participants and by offering zero- to low-cost services.


In terms of the beginning investor, the mutual fund fees are actually an advantage relative to the commissions on stocks. The reason for this is that the fees are the same, regardless of the amount you invest. Therefore, as long as you meet the minimum requirement to open an account, you can invest as little as $50 or $100 per month in a mutual fund. The term for this is called dollar cost averaging (DCA), and it can be a great way to start investing.

Leverage simply means the use of borrowed money to execute your stock market strategy. In a margin account, banks and brokerage firms can loan you money to buy stocks, usually 50% of the purchase value. In other words, if you wanted to buy 100 shares of a stock trading at $100 for a total cost of $10,000, your brokerage firm could loan you $5,000 to complete the purchase.

The stock market works like an auction, and buyers and sellers can be individuals, corporations, or governments. When there are more sellers than buyers, the price of a stock will go down. When there are more buyers than sellers, the price will go up. A company's performance doesn't directly influence its stock price; it's investors' reaction to the performance that decides how the stock fluctuates. If a company is performing well, more people will want to own the stock—consequently driving the price up. The opposite is true when a company underperforms.
