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.
More than anything this is what we really need, big companies accepting bitcoin is without a doubt a good news and it is something that we had been expecting for a long time but if those companies are the only ones that accept bitcoin then sooner or later they will end up with a great deal of the supply, we need that small businesses begin to accept bitcoin as well even if right now they are not going to get as many clients because bitcoin is not as popular, eventually they will make a name for themselves if they accept cryptocurrencies, and they will gain a larger share of local users when bitcoin finally becomes popular.
