Is MXC Takeshi's castle?

Could you please clarify the connection between MXC and Takeshi's Castle? It seems like a bit of a stretch to equate the two, as MXC appears to be a cryptocurrency exchange platform, while Takeshi's Castle is a popular Japanese game show. Is there some underlying reference or context that I'm missing here? Or is this perhaps a joke or play on words that I'm not fully understanding? I'd appreciate any clarification you can provide.
