No, it's not a Trojan horse. The central banks and the gubmint are busy socking away bitcoin and ether in large amounts. They can crater both anytime they want just by dumping their holdings. They don't need a trojan horse or a code bug to do this. Casting aspersions on Ethereum itself is counterproductive though.
As I detailed in the article, this could and likely is a multifaceted plan. Using Ethereum to tank the market is not exclusive to also buying up large amounts of Bitcoin and other coins in order to obtain a controlling stake.
