A hacker attack on Binance, described as the largest cryptocurrency broker in the world, has reignited a question that many investors prefer to avoid: where the assets deposited in a broker actually are and who has power over them. According to Times Brasil, the estimated impact of the episode is US$6.3 billion, equivalent to around R$34 billion.
According to the same report, the investor remains the owner of the cryptocurrencies he deposits with a broker. In practice, however, the portfolios and movement of these resources are largely handled by the company responsible for custody. It is this distance between formal ownership and operational control that the case has highlighted.
The protection of these assets, according to Times Brasil, depends on several elements at the same time: the broker's internal systems, the management of private keys, the authorization of transactions and employee access control. Security, therefore, is not limited to technology. It goes through processes and people.
There is still a relevant technical difference when it comes to blocking stolen resources. According to Times Brasil, Tether and Circle are able to block certain stablecoins, but bitcoin and ethereum do not allow blocking in the same way and depend on other mechanisms to block the movement of diverted resources.
What is at stake is trust in the centralized custody model, in which the client delegates the custody of their assets to a company. For those who operate, the discussion stops revolving only around the price and starts to include where the asset is stored, who can move it and what instruments exist to react to an incident.
What changes for the investor
With the data released so far, it is not possible to estimate what the effect of the episode will be on prices. What the case makes clear is that the assessment of a brokerage begins to consider, in addition to fees and liquidity, the custody structure, internal access control and the ability to block misappropriated assets. For those who defend free markets and clear rules, the episode reinforces the importance of transparency regarding custody and the responsibility of those who guard other people's resources. It is up to each investor to evaluate these points before deciding where and how to keep their assets.
