How high can a doge killer go?

Excuse me, but could you elaborate on what you mean by "doge killer"? Are you referring to a particular cryptocurrency or investment strategy that aims to profit from the decline in the value of Dogecoin, a popular meme-based digital currency? Assuming you are asking about the potential upside for an investment that is designed to short Dogecoin or otherwise benefit from its price dropping, it's important to understand that predicting the future performance of any asset, including cryptocurrencies, is inherently uncertain. Cryptocurrency markets are highly volatile and influenced by a wide range of factors, including but not limited to news events, regulatory changes, and sentiment among investors. As such, it's impossible to definitively say how high a "doge killer" investment could go, as this would depend on a multitude of variables that are difficult to predict. That being said, if you're considering investing in a strategy that aims to profit from the decline of Dogecoin, it's crucial to carefully research and understand the risks involved, as well as the potential rewards. Always remember that investments in cryptocurrency and other high-risk assets should be approached with caution and as part of a diversified portfolio.
