Hidden fees can quietly reshape the cost of buying cryptocurrency. In this episode, Julien Vallet, co-founder of Finst and a former DEGIRO executive, explains why beginners should look beyond the headline commission and understand how spreads, platform design and custody arrangements affect a trade. His account also offers a behind-the-scenes look at building a crypto business: Vallet says he persuaded former colleagues to back the idea, raised €2 million without a formal pitch deck and launched Finst around the period of the FTX collapse.
In brief: The conversation explores hidden fees, the difference between a broker and a crypto exchange, the selection of more than 400 digital assets, and how MiCA is changing the conversation around crypto regulation. A striking story about recovering €266,000 in cryptocurrency from an old phone brings the practical stakes of custody into focus. For beginners, the central message is simple: understand what a platform charges, how it safeguards assets and what risks remain before placing a trade.
Julien Vallet on hidden fees and crypto trading costs
A trading fee is only one part of the price a customer may pay. The spread—the gap between the price at which an asset can be bought and the price at which it can be sold—can also affect the final cost, even when a platform advertises low commissions. That is why comparing trading fees fairly means checking the full transaction, not just the most visible number.
Imagine a new investor buying a small amount of Bitcoin through two services. One displays a low commission but offers a wider spread; the other shows its charges more clearly. The second option may be easier to assess, but the investor still needs to compare the actual buy and sell prices. Transparency means being able to see how a trade is priced before committing funds.
Broker or crypto exchange: why the distinction matters
A broker generally provides a route to buying and selling assets through its service, while a crypto exchange typically brings buyers and sellers together in a marketplace. In practice, services can combine features of both, so beginners should examine how orders are handled and where prices come from rather than relying on a label alone.
Vallet’s experience in online brokerage gives the discussion a useful point of comparison with traditional investing. Yet cryptocurrency has its own considerations: assets may be highly volatile, custody arrangements differ, and a displayed price does not by itself explain every cost. A sensible first step is to review the platform’s pricing information and compare it with other cryptocurrency platforms.
Finst, asset segregation and investor protection
One of the episode’s key topics is how a platform handles customers’ assets. Asset segregation refers broadly to keeping customer holdings separate from a company’s own funds, a distinction that matters if the provider faces financial or operational trouble. It is not a promise that prices cannot fall or that every risk disappears, but it is an important part of understanding custody.
The story of a crypto wallet worth €266,000 recovered from an old phone makes the issue tangible. Access to digital assets can depend on devices, credentials and recovery procedures; losing access may be very different from losing a password to an ordinary online account. For anyone starting out, investor protection begins with understanding both the platform’s safeguards and the responsibilities that remain with the user.
MiCA and the changing expectations for crypto platforms
European crypto regulation is another central theme. MiCA establishes a shared framework for parts of the crypto-asset market in the European Union, giving providers clearer requirements and users a more consistent basis for assessing services. Regulation can improve accountability, but it does not remove market risk or guarantee a positive investment outcome.
For a beginner, the practical question is whether a provider explains its status, services and safeguards in plain language. Readers can explore how European authorities approach the sector in this guide to crypto regulation in France, and see how MiCA authorization is discussed in the case of a French crypto platform. Clear rules help set expectations; careful research remains essential.
Choosing cryptocurrency listings and understanding tax obligations
Finst offers access to more than 400 cryptocurrencies, but a large catalogue is not automatically a sign that every asset is suitable for every investor. Vallet discusses how platforms select the assets they make available, a process that matters because projects differ in liquidity, history, technology and risk. A listing should be treated as access to an asset, not as an endorsement or a recommendation to buy it.
The episode also touches on tokenization, which uses blockchain-based tokens to represent certain assets or rights. The idea may connect digital-asset markets with parts of traditional finance, but the details depend on the asset, legal structure and service involved. Before investing, a beginner should be able to explain what they are buying, what could affect its value and how they might exit the position.
Fees, taxes and a more informed first trade
Costs do not end when a trade is complete. Depending on the investor’s circumstances and local rules, selling or exchanging cryptocurrency can create tax obligations that need to be tracked. Keeping records of transactions, dates and amounts can make later reporting easier; this overview of crypto taxation in France provides further context.
Vallet’s account links the mechanics of trading with broader questions about safety and market conduct. The useful lesson for a newcomer is not to chase the largest selection or the lowest advertised fee, but to compare the complete service: pricing, custody, regulatory information and the risks of the assets themselves. Good crypto decisions start with questions asked before the trade—not after it.
