Just to be clear - Minerals never received any threats. The picture you quoting is from other e-sports coin thread. We decided to take out screenshots of SCII and elements of design that we took from the game just to play safe.
Quick response and action from the devs. Even if Blizzard Entertainment decides to issue a takedown notice, can they really do anything? It's a decentralized currency system, they can't do anything to officially take it down! Now that all ties to SC2 franchise are removed there is almost no chance Minerals would suffer the same consequences as LOL.
