History shows that investing in stocks is one of the most efficient ways to build wealth over time. Nearly every member of the Forbes 400 list of wealthiest Americans got there because they own a large block of shares in a public or private corporation. Learning to invest wisely and with patience over a lifetime can yield a portfolio far outpacing the most modest income.
In that case, it is possible to invest passively in capital markets. This means that a private investor puts aside either a lump sum or an amount each month and the money is invested into a fund. That fund contains the savings of lots of other private investors and is managed by a professional equities investor. The fund will then be invested in an equity market (such as the NYSE) or a sector (such as energy).
The stock exchanges also maintain all company news, announcements, and financial reporting, which can be usually accessed on their official websites. A stock exchange also supports various other corporate-level, transaction-related activities. For instance, profitable companies may reward investors by paying dividends which usually comes from a part of the company’s earnings. The exchange maintains all such information and may support its processing to a certain extent. (For related reading, see "How Does the Stock Market Work?")
This survey was conducted online within the United States by The Harris Poll on behalf of NerdWallet from June 14-18, 2018, among 2,024 U.S. adults ages 18 and older, among whom 787 were invested in in the stock market during at least one of the past five financial downturns. This online survey is not based on a probability sample and therefore no estimate of theoretical sampling error can be calculated.

Stockbrokers, also known as registered representatives in the U.S., are the licensed professionals who buy and sell securities on behalf of investors. The brokers act as intermediaries between the stock exchanges and the investors by buying and selling stocks on the investors' behalf. An account with a retail broker is needed to gain access to the markets.

ECN/Level 2 quotes: ECNs, or electronic communication networks, are computer-based systems that display the best available bid and ask quotes from multiple market participants and then automatically match and execute orders. Level 2 is a subscription-based service that provides real-time access to the Nasdaq order book composed of price quotes from market makers registering every Nasdaq-listed and OTC Bulletin Board security. Together, they can give you a sense of orders being executed in real time.
On when to buy, my recommendation is to avoid jumping into the pump train when you see a cryptocurrency price rising very fast. Fear of missing out is a very potent psychological trigger for us humans and if you see something rising fast the first thing you’ll want to do is buy some so that you don’t feel left out. Go for the dip, but go for the dip reasonably: identify the cryptocurrencies you want to own, ideally solid ones based on your own research (it’s important not to invest in crappy projects), and when you see them taking the plunge go grab some big chunks.
The stock exchange shoulders the responsibility of ensuring price transparency, liquidity, price discovery and fair dealings in such trading activities. As almost all major stock markets across the globe now operate electronically, the exchange maintains trading systems that efficiently manage the buy and sell orders from various market participants. They perform the price matching function to facilitate trade execution at a price fair to both buyers and sellers.
