Include links to aid reading, I had to go search for "Bjorka" to see the news about the identity so I could be on the same page with you, some people will not do that.

So far Bjorka has mainly attacked government data, cryptocurrency is not related to government data, so it is highly unlikely that Bjorka will shift attention to the crypto space shortly. The government of Indonesia are already taking measures to ensure that they clamp down on this hacker and have put this hacker at the center of their focus, They may record success soon before maybe Bjorka decides to switch attention to cryptocurrency.
