Since the underlying businesses operate in differing markets, sectors and countries, their quoted prices move independently as supply and demand in them rises and falls and new information is released to the public about the current business situation. It is the changing of prices that offer investors the opportunity to make a capital gain (or loss) via ownership.
You may decide to invest ad-hoc or on a regular schedule basis. You may for example want to invest 40% of your allotted funds into mainstream, “secure” investments such as Bitcoin, Ethereum or Zcash. You may decide to spread out the remaining 60% to cryptocurrencies listed in the top 20 or top 30 projects based on capitalization on coinmarketcap, if you feel this is a secure strategy.
Before you start buying cryptocurrency, you must understand some concepts about investing. Remember, cryptocurrency markets are not regulated, so investor sentiment is aggravated by rumours, people spreading false information, « pump and dump » actions, « sell walls », FOMO (fear of missing out) and all sorts of manipulations including insider trading. Knowing these will hopefully help you rationalise your actions.
Diversification allows you to recover from the loss of your total investment (20% of your portfolio) by gains of 10% in the two best companies (25% x 40%) and 4% in the remaining two companies (10% x 40%). Even though your overall portfolio value dropped by 6% (20% loss minus 14% gain), it is considerably better than having been invested solely in company E.
Once you are familiar with the concepts above, and know that you can (and eventually will) be influenced, you need to do some research on what projects you want to invest into. There are to date 1400+ cryptocurrency projects listed on coinmarketcap, a website that tracks projects, market value etc. This is a good start to understand market capitalisation, price of the cryptocurrency unit in what we understand when we begin (fiat currency i.e. dollars or anything else), total amount of assets in circulation etc.
The exchange may offer privileged services like high-frequency trading to larger clients like mutual funds and asset management companies (AMC), and earn money accordingly. There are provisions for regulatory fee and registration fee for different profiles of market participants, like the market maker and broker, which form other sources of income for the stock exchanges.
Discount brokers used to be the exception, but now they're the norm. Discount online brokers give you tools to select and place your own transactions, and many of them also offer a set-it-and-forget-it robo-advisory service too. As the space of financial services has progressed in the 21st century, online brokers have added more features including educational materials on their sites and mobile apps.
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.
Dollar-cost average: This sounds complicated, but it’s not. Dollar-cost averaging means investing a set amount of money at regular intervals, such as once per week or month. That set amount buys more shares when the stock price goes down and fewer shares when it rises, but overall, it evens out the average price you pay. Some online brokerage firms let investors set up an automated investing schedule.
