I am also waiting for the announcement of the next giant that will start accepting and investing in cryptocurrencies. I'm sure it won't be Facebook because of the Libra project. Gates also don't like crypto, so I doubt it will be Microsoft. Apple is the most likely, followed by Amazon.
However, the most important thing is that small companies should not be afraid of cryptocurrencies and start accepting them. I think it is already happening.
The Libra/Diem project of FaceBook was dead even before it could be launched. Rather than a cryptocurrency, it was more similar to the CBDC coins so I am not much worried about its demise. Maybe now Zuckerberg will realize his mistake and start trusting in Bitcoin, rather than creating his own shitcoin. And I agree with you regarding Bill Gates. His stance towards cryptocurrency is not very encouraging. But the important thing to note here is that Gates is no longer the CEO of Microsoft. As of now, Satya Nadella is holding that position. But I agree with your last post. Apple and Amazon are much more likely than either Facebook or Microsoft to adopt Bitcoin in the short term.
