Since this is happening worldwide in many banks, it seems that this is a planned strategy from the banking industry.

They want people to deposit money into the banks, and the banks tell them they have "Bitcoin", when in reality the people don't have control of those Bitcoins, if they even exist.

Bitcoin is decentralized, there's no need for a bank to hold your Bitcoin.

> “The first cryptocurrency to exist,” Nubank’s app says as the user navigates to the page to buy BTC. “Bitcoin was created with the intention to decentralize the financial system and influenced all the other cryptocurrencies since then.
