Emergency fund: what it is and why it is essential

Emergency Fund: what it is and why it is essential

The emergency fund serves as a personal treasury for unexpected events, and it can be a lifesaver. How is it created, and what is its significance?

Many people recognise the emergency fund as a well-known concept, but often postpone creating it. The reason for this is straightforward: an emergency is an unpredictable and distant event that tends to seem less urgent than immediate issues with tight deadlines. However, when an emergency does occur, it can lead to significant stress and anxiety. In this article, we will explore why building an emergency fund is essential and provide a step-by-step guide on how to do it.  

Have an emergency fund: Be the ant in a world of cicadas.

The importance of the emergency fund has been part of human culture since time immemorial, if we think that Aesop wrote the fable of ‘The Ant and the Cicada‘ more than two thousand years ago. Admittedly, the Greek author does not tell us about the emergency fund, but he makes us realise how important it is to arrive prepared for the challenges that life, sooner or later, presents us with. The cicada sings all summer and does not worry about winter. At the same time, the ant slowly accumulates the necessary supplies: the cold arrives, the cicada goes hungry, and the ant serenely enjoys the fruits of its labour

This moral, although simple and obvious at first glance, shoves reality in our faces. We know perfectly well that the future will come knocking sooner or later, but despite this, we are only willing to take the initiative when we feel the breath on our necks. The result? Total unpreparedness mixed with panic and stress. 

The emergency fund serves precisely to avoid these unpleasant situations and to continue living our lives in peace, regardless of accidents, surprises or sudden desires. It allows you to buy a new phone, repair your car, or even go see Green Day in Florence without having to – a random example – sell the Ethereum you staked on Young Platform. Now that its usefulness is obvious, let’s see how to build an emergency fund, step by step. 

Creating an emergency fund is challenging, but it can be done.

Before proceeding to set aside finances, one must understand one’s savings goal because it is uninspiring and unwise to hoard money to the bitter end. To do this, you need to track and analyse your monthly expenses, fixed and extra, such as rent, petrol, food, subscriptions and so on. You can write them down in pen, use Excel or make your life easier with a budget management app. Now, multiply the figure by three or six, depending on your needs: the result of this complex mathematical operation equals your savings target, because the primary purpose of the emergency fund is to allow you to live without a fixed income. Once you have worked out how much you need to save, creating a strategy to make it a reality is time.

Putting money aside is a test of great discipline: the art of saving has to come to terms with the human soul and its irrepressible and impulsive desire for gratification. Moreover, it is exhausting when the goal is a large sum of money because it seems so far away. To reduce this cognitive load, specific strategies allow you to reach your goal by taking advantage of time, i.e., by installing the set amount in periodic instalments. Of these, the famous 52-week challenge would take you a year to build up your emergency fund. If, on the other hand, you want to speed things up, the advice is to make a kind of accumulation plan and withdraw a fixed amount of money. In this case, remember the teaching of the well-known book ‘The Richest Man in Babylon‘: if you receive a fixed monthly income, take it out and then live on the rest, never the other way around. This means that if you earn €1,300 a month, you first take out €100 and then recalibrate your life based on the €1,200 that remains, as if the €100 had never existed. 

Let us give a practical example to avoid any doubt. Our example is Mario, a 28-year-old boy living in Milan who works as an office clerk. Mario writes down everything for a month and discovers that his essential expenses amount to about €1,185, divided as follows: 

  • 750€ rent per month for a two-room apartment (he was fortunate)
  • 100€ bills
  • 45€ internet (Wi-Fi and mobile)
  • 40€ vehicle subscription 
  • 250€ supermarket shopping 

Mario decides it is time to start thinking about an emergency fund. He is 28 years old, young and knows that if he loses his job, he will be able to find another one in a relatively short time. His fund, therefore, should correspond to four months’ expenses: 1185 x 4 = 4740€. He rounds up and opts for the 5,000€. At this point, he will just have to figure out how to accumulate it. 

Perfect. You know how much you have to save, and you also know how to do it. The time has come to work on self-control. Of course, being rigorous and consistent in saving does not imply embracing asceticism: nobody is asking you to be the new Mahatma Gandhi. It just means concentrating and understanding what you really need. An interesting technique is to wait until the next day and ask yourself, “Do I still need that limited edition poster with Walter White and Gus Fring having lunch in Los Pollos Hermanos?” Yes, you will still need it. But you have been practising, and this exercise might save you a little extra next time. 

Nice but… the emergency fund has a big problem.

Your emergency fund now exists and is no longer just a good New Year’s resolution. However, it doesn’t end there, there is still one hurdle to overcome, the number one enemy of savings, the final boss: inflation. Indeed, in theory, this liquid treasure you have built up with so much effort, like a bit of ant, is destined to stay put for quite a while – knock on wood – because it is meant for emergencies. The problem is that time passes, inflation rises, and your emergency fund loses value.

You thought you had the solution ready to face the final boss, huh? Super Mario had to cross eight worlds to defeat Bowser and retrieve Peach. All you have to do is sign up below and read the articles we post about it, like this one. Until next time!

BTCFi: What is Defi on Bitcoin and how it works

BTCFi: qu’est-ce que la DeFi sur Bitcoin et comment ça fonctionne

Taproot has enhanced Bitcoin’s competitiveness by introducing new features like smart contracts and decentralised finance (DeFi). This gave rise to BTCFi. What is it all about?

The Taproot update in 2021 enhanced Bitcoin’s competitiveness by improving its efficiency and privacy while enabling features previously outside its protocol, such as smart contracts and decentralised finance (DeFi). Since then, significant progress has been made, leading us to the concept of BTCFi (Bitcoin + DeFi). What does this entail?

DeFi: Finance for all

DeFi, the synthesis of Decentralised finance and Finance, is a universe of financial services that aims to exclude traditional intermediaries—typical of centralised finance—and their associated costs. This is possible because DeFi is built on blockchain and works thanks to smart contracts, self-executing digital agreements written in code and registered on a blockchain. These contracts are automatically activated without intermediaries when predefined conditions occur. 

We have been discussing decentralised finance since 2015, when Ethereum launched smart contracts, which are fundamental to its functioning. This article provides everything you need to learn more about this topic.

Today, the total TVL (Total Value Locked, an indicator that measures the total value of assets deposited in a decentralised finance protocol) in DeFi is around $90 billion, and more than 50 per cent of it is locked up in Ethereum. However, something has changed in recent months.

Taproot: Let the DeFi on BTC begin!

The Taproot update is considered a significant upgrade for the Bitcoin network. It increases its efficiency and privacy and, above all, extends the capabilities of smart contracts. Two main functions, the MAST and Schnorr signatures and Tapscript, Bitcoin’s programming language update, make this possible. We have discussed this in detail here.

Taproot has enabled new possibilities for programmability and privacy within the protocol. These changes naturally also affect Bitcoin, which is gaining use cases

Bitcoin dominates the market but is little exploited in DeFi.

As is well known, BTC represents about 63% of the crypto world’s total market cap, with a value of about USD 1.6 trillion. However, due to the incompatibility between its blockchain and Ethereum, it is tricky for holders to find a secure solution to profit from the asset held. Of course, some ways, such as wrapping and bridging, allow Bitcoin to be ‘transferred’ from its native blockchain to other chains, such as Ethereum.

Wrapping and bridging: risky solutions

The main problem is the security of the transactions, as one is exposed to the risks of the entities involved in these processes: merchants, custody services, and bridges could be subject to attacks and exploits, in addition to the inherent risk of the individual platforms operating in DeFi. However, the main deterrent is only one: Usually, those who hold Bitcoin do not want to part with it for any reason, and these transactions necessarily go through custodial wallets

Hence, there is a need to implement something that meets these demands: DeFi on Bitcoin or BTCFi.

What is Bitcoin DeFi?

BTCFi is an ecosystem of decentralised applications (DApps) of a financial nature built on Bitcoin. As simple as this may seem to be a definition, it carries complex consequences, especially if one relates it to the ‘old’ ways of using BTC in DeFi. The main differences:

  • Network: In Ethereum’s DeFi ecosystem, one has to use WBTC to trade, exposing oneself to the risks we saw earlier. On BTCFi, transactions are processed directly with BTC.
  • Security: Unlike wrapping BTC, which requires trusting the custodian, merchant, bridge, DeFi platforms, and underlying infrastructure, BTCFi is based on Bitcoin’s blockchain, which is unique regarding security and decentralisation.
  • Usage: While WBTC on Ethereum (or other chains) is mainly used as collateral or a medium of exchange in DEX, BTCFi potentially opens up all the use cases of traditional DeFi, as we will see below.
  • Custodianship: While wrapped, Bitcoin is held by a custodian such as BitGo, a centralised entity. BTCFi is natively non-custodial, as it is managed exclusively by decentralised protocols.

The advantages of a native DeFi on Bitcoin are apparent, and Bitcoiners seem to have understood this well. Defillama’s graphs speak for themselves: since April 2024, the TVL on the Bitcoin chain has increased from $490 million to $5 billion, equivalent to 63,000 Bitcoins. 

At the moment, the protocols that have catalysed the most BTC are Babylon, Lombard, and Solv Protocol. The first of the three dominates the ranking, with almost 4 billion (out of 5) Bitcoins on the chain. Lombard and Solv Protocol follow.

BTCFi: How to use it?

As we mentioned, Toot Bitcoin has use cases similar to traditional Bitcoin. The difference is that it is built and developed on the native blockchain without wrapping or bridging. Look at some practical use cases introduced by BTC’s native blockchain protocols.

Staking with Babylon

Babylon, for instance, allows BTC to be put on lockdown on the Bitcoin network to guarantee and actively participate in the security of other Proof-of-Stake networks. This mechanism, which has long been popular on the Ethereum mainnet, is called restaking. In this case, it uses the computing power dedicated to mining BTC by indirectly transferring it onto proof-of-stake networks. All this happens without the user being aware of it, since it is as if he receives rewards by staking his BTC, while on the opposite side, Proof-of-Stake blockchains can exploit locked Bitcoins to improve their systemic security. 

Liquid staking with Lombard and LBTC

Lombard also offers a similar service with an extra feature: liquid staking. Once one’s BTC is locked up, one can mine LBTC, an asset collateralised 1:1 with Bitcoin, to generate additional income. Due to its cross-chain nature, it is possible to use LBTC ‘around’ DeFi, as collateral for lending and borrowing, or even to provide liquidity to DEX. In short, LBTC is the equivalent of stETH for BTCFi.

Solv Protocol: towards unified liquidity

Finally, Solv Protocol, which offers restaking services, issues a version of BTC called SolvBTC. This represents an interesting attempt at BTC wrapping because it aims to solve the problem of Bitcoin’s fragmented liquidity: the various wrapped versions of BTC – WBTC, BTCB, BTC.b, etc. – are chain-specific and have little cross-chain interoperability, resulting in de facto ‘siloed’ Bitcoin. – The various wrapped versions of BTC – WBTC, BTCB, BTC.b, etc. – are chain-specific and have little cross-chain interoperability, being in fact ‘siloed. ‘ 

SolvBTC aims to unify Bitcoin’s liquidity across multiple chains as a universal BTC pool for DeFi’s users. This will allow for more agile asset use across different protocols. 

Advanced liquid staking: SolvBTC.LSTs

In addition, Solv Protocol, like Lombard, also has liquid staking functionality since you get SolvBTC by blocking SolvBTC.LSTs (SolvBTC Liquid Staking Tokens) in return. These, in turn, are divided into Pegged LSTs, which are pegged 1:1 to the value of Bitcoin, and Yield-Bearing LSTs, which grow in value over time because the revenue gained from the stake is automatically reinvested in the token.

We are only at the beginning of BTCFi

As you may have guessed, this is a newly developing world with infinite return opportunities: using your Bitcoins in DeFi while maintaining custody, without necessarily having to use WBTC, was a long-overdue possibility.
