Crypto investing data

Lesson in Course: Crypto (advanced, 8min )

What should we be looking for when comparing crypto?

Successful investing requires us to equip ourselves with information. Laws and regulations require essential information about traditional investments (stocks, bonds, ETFs, and mutual funds) to be made available to investors. While crypto's decentralized nature makes the same data hard to come by, here are some basic metrics that we can use when comparing cryptocurrencies to invest.

Crypto market capitalization / market cap 

A crypto's market cap represents its total value in terms of another currency, such as US dollars

Example crypto market cap calculation

We create a total of 1,000 Medes coins, and each one is worth $100. This means that the market capitalization of Medes coin is $100,000 -> 1,000*$100

We can use a crypto's market cap to gives us a sense of its adoption and growth better than the price alone, especially when used with the other factors of supply and volume.

For instance, price alone can be misleading since one cryptocurrency may have a higher per-coin price but a lower market cap than another cryptocurrency due to differences in the supply. Or, two cryptocurrencies can have the same market cap, but one may have more utility and a larger community using it, which are signs of better growth potential.

In general, cryptos with smaller market caps tend to be riskier but have higher growth potential than larger market caps. We can diversify some of the risks by holding various cryptos with a range of market caps.


A crypto's supply, the total number of coins or tokens, directly impacts its value. Keeping everything the same, increasing the supply will lower the value of the coin or token.

Some coins are similar to cash and other fiat currencies because they are minted, or created, indefinitely. There is an unlimited supply, so its value will erode over time. 

For example, we could purchase an ice-cream cone or a cup of coffee in the 1930s for 5 cents -- that same 5 cents can't buy the same ice-cream cone or coffee today. The dollar's value has gone down, and the same will happen for many cryptocurrencies. We call this phenomenon inflation, and cryptos like this are considered inflationary

Some cryptos, like Bitcoin, are the opposite. There is a fixed amount that we can ever mine, much like the amount of gold in the ground. We call these cryptos deflationary.  

Similar to gold, the fixed supply means that it will increase in value relative to inflationary cryptos and cash over time. The imbalance between the supply causes the increased value. For instance, the number of Bitcoin is flat, so it will take more US dollars to buy one Bitcoin as the government creates more dollars over time.



A crypto's volume shows us how much of it is actively traded and reflects its liquidity.

Higher volumes tend to lead to more stable prices because there are plenty of buyers and sellers, making it easy for us to transact at the market price. However, major news or events can create a sharp spike in volume and destabilize prices when investors are frantically trying to buy or sell.

When the volume increases, the price will generally move in the same direction. As more people are buying a crypto (increasing the volume), its price will rise, attracting more folks to buy, and the cycle continues. 

Many exchanges or data services aggregate 24-hour trading volume in fiat denominations, like the US dollar, as shown in the image below.

Here is an informational toolkit for additional resources to follow the crypto markets:

We need to know as much as we can about a cryptocurrency before investing. Using this information to identify the differences between cryptocurrencies will prevent us from losing money in case we mistakenly invested in a riskier one than we thought.

As a general rule of thumb, higher market caps, higher volume, and deflationary crypto will have more stable prices and relatively less risk. Lower market caps, lower volume, and inflationary coins are riskier but could also have more potential growth for better returns.
