When you buy some cryptocurrency, the money will be withdrawn from your bank account or card and you will be credited in your exchange in a sum matching the cryptocurrency you have purchased.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.
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.

While today it is possible to purchase almost everything online, there is usually a designated market for every commodity. For instance, people drive to city outskirts and farmlands to purchase Christmas trees, visit the local timber market to buy wood and other necessary material for home furniture and renovations, and go to stores like Walmart for their regular grocery supplies.
Arbitraging can be very lucrative especially with Asian markets (South Korea for example) where cryptocurrencies are exchanged at premium rates, but due to the high volatility of the markets and the congestion on major cryptocurrencies (Bitcoin and Ethereum) it is becoming increasingly difficult to do arbitraging because of potential incurred losses. Add to this the fact that exchanges need a certain amount of confirmations before balances are made available for trading and it makes it quite risky at least for Bitcoin and Ethereum.
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.)

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."
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).
The biggest obstacle to stock market profits is an inability to control one’s emotions and make logical decisions. In the short-term, the prices of companies reflect the combined emotions of the entire investment community. When a majority of investors are worried about a company, its stock price is likely to decline; when a majority feel positive about the company’s future, its stock price tends to rise.

Investing is a way to set aside money while you are busy with life and have that money work for you so that you can fully reap the rewards of your labor in the future. Investing is a means to a happier ending. Legendary investor Warren Buffett defines investing as "… the process of laying out money now to receive more money in the future." The goal of investing is to put your money to work in one or more types of investment vehicles in the hopes of growing your money over time.
Understand that for both beginning investors and seasoned stock market pros, it's impossible to always buy and sell the best stocks at exactly the right time. But also understand that you don't have to be right every time to make money. You just need to learn some basic rules for how to identify the best stocks to watch, the ideal time to buy them, and when to sell stocks to lock in your profits or quickly cut any losses.
Bob wants to buy Ethereum. He only has Bitcoin. On an instant-access exchange, he will trade Bitcoin for Ethereum. He will provide the target address of his Ethereum wallet to receive the Ethereum he wants to purchase, and he will also provide a refund address for Bitcoin, most likely the address from which he will be sending his Bitcoin to the exchange. Once he will submit the order, Bob will be asked by the exchange to send the necessary amount of Bitcoin to an address. Once he will send this money and it is confirmed, the instant-access exchange will handle all the buy/sell operations on his behalf, and will send the Ethereum once the order has been fulfilled.
The exchange also earns from selling market data generated on its platform - like real-time data, historical data, summary data, and reference data – which is vital for equity research and other uses. Many exchanges will also sell technology products, like a trading terminal and dedicated network connection to the exchange, to the interested parties for a suitable fee.

Finally, one point to mention is that a given cryptocurrency can be listed in more exchanges, with different listing prices (see below – Arbitraging). The best place to look for a cryptocurrency listing in term of total market capitalisation is Coinmarketcap. Cryptocurrencies are listed per descending order of market capitalisation; the site also allows to deep-dive on each cryptocurrency to see their value over time and where they are listed. Some cryptocurrencies may be listed on several exchanges but only 1 or 2 exchanges may see the critical mass of transactions taking place.
Phrases like “earnings movers” and “intraday highs” don’t mean much to the average investor, and in many cases, they shouldn’t. If you’re in it for the long term — with, say, a portfolio of mutual funds geared toward retirement — you don’t need to worry about what these words mean, or about the flashes of red or green that cross the bottom of your TV screen. You can get by just fine without understanding the stock market much at all.
By knowing how much capital you will need and the future point in time when you will need it, you can calculate how much you should invest and what kind of return on your investment will be needed to produce the desired result.
