Storing them in banks is such a bad idea, especially if they are using it for protests. If they could have stored it in Bitcoin, the police and government cannot stop them as they do not own or control the blockchain technology.
The problem with digital banking is that the government will always control and have the power to freeze your account whenever they want without any warning and that can extend to other scenarios too, so the idea of digitization should be protested by any means as the purpose of digital transaction is to have complete control over their citizens.
But how
BTCitcoin can help in these scenarios depends upon how a government is open to the new technology and if they think they are bypassing their control through
BTCitcoin then they will impose a ban for that too but they cannot freeze their account and that is an advantage but it will be difficult for them to access the funds easily with restrictions.
