This is totally false. Other blockchains have sold the false idea that to power down is to harm the blockchain, the reality is that if the option exists then you can use it. It is up to each user to use their funds as they see fit. In blurt there are no silly rules, whoever gave you that information has only brought the absurd mentality of the blockchain where if they tell you publicly that if you do power down you will not receive votes of any kind, that is blackmail.
