What Is ROI in Crypto?

ROI stands for return on investment. It is one number that says what you got back compared with what you put in, written as a percentage. The formula is short: take what your coins are worth now, subtract what you paid, divide by what you paid, then multiply by 100. Put 200 dollars into Ethereum, watch it become 260, and your ROI is 30 percent.

What does the number actually include?

Less than most people assume. The raw formula ignores everything except the two prices, and crypto quietly charges you at several points along the way: the exchange takes a fee when you buy and again when you sell, the network takes a fee when you move coins, and the gap between the buy and sell price — the spread — takes a little more. A more honest ROI counts every dollar that left your pocket, not just the purchase price. Depending on where you live, tax may take another slice when you sell.

Why can a huge percentage still be a small win?

Because a percentage has no size of its own. It is a ratio, like a speed: 300 percent sounds thrilling, but 300 percent of 20 dollars is 60 dollars. Screenshots posted online almost always show the percentage and hide the amount, which is exactly why they are posted. It also matters whether the gain is real or on paper. Until you have actually sold, your ROI is a number on a screen that moves every minute, and plenty of people have watched a large one shrink to nothing while waiting for a larger one.

How do you compare two investments fairly?

Add time. Twenty percent in a month and 20 percent in three years are wildly different results, so note when you bought as well as what you paid. It also helps to compare against simply holding bitcoin over the same stretch, which is the benchmark most of the market uses anyway.

Keep a plain record: date, amount spent, fees, and what you received. A spreadsheet with four columns will tell you more about how you are doing than any portfolio app's headline percentage, and it is the only version of your ROI that survives contact with reality.
