Your thread title is also as misleading as what we see on news sites: "Hackers claim $2 million in bitcoin" is different from hackers demanding $2 million in bitcoin. Your topic title made me see the entire situation, like the hackers already got their hands on the bitcoin, which makes me almost want to ask if there were some bitcoin wallets linked to the game data that were stolen.
 
But why do hackers always go for bitcoin as demand? Why not ask for other coins that could also be used and exchanged for whatever they want without being traced? There are coins like Monero (XMR), which is a highly recommended privacy coin. Why is it always bitcoin? Making the news and headlines look like bitcoin is always used for illegal things, and all of that as if it's the only coin that could be used by criminals and it won't be traced.
