Brazil's B3 exchange recently launched a new product, offering event contracts linked to Bitcoin for ultra-high-net-worth clients. Basically, it allows wealthy individuals to play with derivatives based on Bitcoin trading, rather than holding the coins directly. This idea is quite interesting; it seems to be testing institutional investors' demand for Bitcoin trading. Previously, the focus was mainly on spot trading, but now they are starting to develop contracts. Does this mean traditional financial institutions are also beginning to take Bitcoin trading seriously? Actions in South America are quite swift. Do you think this type of event contract could become a new trend?
