Diversification: what it is and why it is important 

Diversification is one of the fundamental concepts of investing, even though too many people dismiss it. But what is it? And why is it so important? 

Diversification is a fundamental principle that should guide the investment strategy of anyone who wants to enter the world of crypto. It is a concept that belongs to traditional finance, but one that has accompanied humanity throughout the entire process of civilisation. In this article, we will try to answer two questions that are as simple as they are comprehensive: what is diversification? And why is it so important?

Diversification: what is it and what does it mean?

In finance, diversification is defined as a strategy or fundamental principle for minimising risk: in concrete terms, it means spreading financial resources across a diverse range of assets, rather than concentrating capital on a single investment. The prime example, the timeless classic used by those who want to explain this concept in a simple way, is that of eggs in a basket. More precisely, the phrase ‘don’t put all your eggs in one basket!‘, accompanied by an index that swings back and forth, solemn as an oracle. 

Joking aside, the comparison is apt: diversification means avoiding putting all your eggs in the same basket. The reason is simple: if all your eggs are in one basket and, unfortunately, it slips out of your hands, you’ll end up with an inedible omelette. In other words, you would have lost everything. But if the same number of eggs had been wisely distributed across several baskets, you would have lost the contents of one of them, preserving the rest. Similarly, as you can easily understand, spreading your investments across several different assets greatly reduces the risk of losing everything in one fell swoop. And your portfolio will thank you for it.

If you think about it, as we mentioned in the introduction, this rule has been around for centuries, since the dawn of civilisation. As early as the Neolithic period, communities raised several types of livestock at the same time – including cows, sheep and goats – in order to have different qualities of food and material resources available, but also to prevent, for example, a single disease from wiping out all their animals. Even during the Middle Ages, farmers understood the importance of growing several types of cereals using a three-year rotation system. The advantages were obvious: improved soil fertility, increased overall production and reduced risk of famine, as losses caused by a bad harvest were offset by the others. 

Among other things, diversification also determines our diet. Obviously, it would be wonderful to eat pizza every day, but it is essential to alternate with healthier, more boring foods to avoid digging our own graves. In short, if diversification guides every aspect of human life, why shouldn’t it do the same for our investments?

Diversification: Why is it important?  

Diversification, as previously explained, is an essential criterion from a conservative perspective, i.e. risk reduction. At this point, one might rightly object: ‘I don’t care about risk, I want to put all my money on that meme coin and become a millionaire in three days’. Fair enough, but this is not investing; it is gambling, and the chances of winning when gambling are extremely low. Returning to investing, diversification also makes sense from a profit perspective, as it allows you to avoid missing out on the asset or assets of the decade. 

Let’s take a concrete example from the internet megatrend of the early 2000s, just after the dot-com bubble burst. At that time, the main use case for the internet was search, and Google was the undisputed king. You could have legitimately thought that the Californian company was the only horse worth betting on, as it dominated almost non-existent competition. Today, that choice would have undoubtedly proven you right, as Google’s share price has grown by more than 6,000%, but you would have kicked yourself. Why? By viewing the internet as a tool designed exclusively for online search, you would have missed out on other companies such as Netflix and Amazon, which have outperformed Google by carving out their own slice of the market. 

Diversifying in the crypto world

Diversification in the world of cryptocurrencies follows the dynamics of the example just described: it depends on how you understand blockchain and its use cases. Bitcoin is, without a doubt, the dominant player in this world, as it alone accounts for more than 64% of the market. However, its usefulness is ‘limited’ – for now – to payments and being a store of value, although BTCFi could show promise. So, if you believe that blockchain will not go beyond Bitcoin, then it makes sense to invest everything in it, at your own risk. 

It is undeniable, however, that blockchain is slowly but surely making its way into other strategic sectors, and the future could hold surprises in this regard. The key point is to take a step back and look at the situation as a whole: don’t focus on the present so as not to be misled by heuristics and cognitive biases, but, as the philosopher Baruch Spinoza would say, consider things sub specie aeternitatis – in the light of eternity – in an absolute and universal sense. This is precisely what diversification means: avoiding overexposure to a single cryptocurrency, both to reduce risk and to avoid missing out on huge opportunities such as Ethereum, which rose by 1,880% between 1 January 2020 and 1 January 2025. 

Clearly, in order to invest wisely, you need to stay up-to-date and stay on top of what is happening in this constantly evolving world.
