You're telling me the app takes the money and never gives it to Starbucks??? Give it up, you've already lost this argument. It's no big deal that I am right and you are wrong. This isn't a life or death matter. Stop trying to twist it around to make it seem like no company accepts Bitcoin. Even if a company uses an app to accept it, then that just means that that app can be used by multiple companies to accept Bitcoin, proving you even more wrong than you already are.
And this thing that you keep saying that Bitcoin will go up because of speculation, well I agree with some of it, but I don't think that's 100% of the reason it will go up. Because more investors as you already know see it as a store of value. Now I agree it will never become a frequently used currency for goods, it's too slow and takes some work to make a transaction. But that doesn't mean it has no use. Sure, people use it for illegal activity. It's a currency, but that's not why most use it. When you look at the way the world is going, it's inevitable that we will one day turn to digital money. (Signs of the end of times as stated in the illuminati) There really is use for blockchain technology, and it's not about using it on illegal activity, it's about taking control of our own money. It's about being your own bank.
