¿Cuáles son las empresas que invierten en Bitcoin?

I'm curious to know, what companies are currently investing in Bitcoin? Are there any major corporations or startups that have made significant investments in this digital currency? Could you give me some examples of these companies and perhaps discuss their motivations for investing in Bitcoin? Is this trend becoming more prevalent in the corporate world, and if so, what does it mean for the future of Bitcoin and the cryptocurrency market as a whole?
