Diversification in Crypto: How Many Coins Should You Actually Own?
There is a type of crypto investor who owns 47 coins. They have a spreadsheet with 12 tabs. They follow 200 Twitter accounts. They set price alerts for tokens with names like TurboCorgiFinance and MetaRocketMoonDAO. They are very busy. They are not necessarily making money. Then there is another type of investor who owns three coins, checks their portfolio once a week, and sleeps reasonably well at night. The question of how many coins you should own is one of the most practical and most argued-about questions in all of crypto. The answer is not a number. It is a framework. And that framework, built on real data, honest math, and the hard lessons of people who got it wrong, is exactly what this blog is going to give you.

The Egg Basket Problem, Except the Eggs Are on Fire
You have heard the saying. Do not put all your eggs in one basket. It is one of those pieces of advice that sounds obvious until you are standing in a crypto bull market watching a single altcoin go up 400% in two weeks and desperately regretting that you only put 5% in it.
Here is the thing about diversification in crypto: it works differently than it does in traditional investing, and most people do not realise that until they have already made expensive mistakes.
In traditional investing, you diversify across asset classes, geographies, and sectors because different assets tend to respond differently to economic conditions. When stocks fall, bonds often rise. When the dollar weakens, gold often strengthens. These negative correlations are the engine that makes diversification work.
In crypto, almost everything goes up together when Bitcoin goes up. And almost everything goes down together when Bitcoin goes down.
Many altcoins have high correlation to Bitcoin, often above 0.7, meaning when Bitcoin's price falls, they tend to fall too. So if you buy ten different altcoins thinking you have built a diversified portfolio, what you may have actually built is ten slightly different bets on the same thing. You feel diversified. You are not.
This does not mean diversification in crypto is pointless. It means it has to be done intelligently, with an understanding of what diversification actually achieves and what it does not.

Why Diversification Exists in the First Place
Before we get into how many coins to own, let us be honest about why diversification matters in crypto specifically.
According to a 2025 CoinGecko report, more than half of all cryptocurrencies listed since 2021 have already died, vanishing completely or becoming ghost tokens with no trading volume or utility. In the first quarter of 2025 alone, a staggering 1.8 million tokens ceased all activity.
