It's true that in this world there are more people who don't trust Bitcoin than people who believe in Bitcoin. Although the majority of people do not believe in Bitcoin, the development of Bitcoin has been very significant. I can't imagine what if the majority of people have started trusting Bitcoin and investing in Bitcoin. It will certainly make the price of Bitcoin very expensive and also most countries should legalize Bitcoin as a legal tender.
I can't wait for this to come true, let time tell. For now I only focus on collecting Bitcoins. So when Bitcoin is getting more and more valuable and people are starting to trust it, then I already have enough Bitcoin and can get a big profit from Bitcoin.
I can imagine. It would mean that bitcoin would be 1+ million dollars each, there would be a lot more places that accept bitcoin. There would be payment processors, like bitpay type of places but global scale with a ton more work and a lot easier.
There would be apps that you use, from your mobile phone, where you pay for something by reading QR code that the business shows you. Which I do not think that would be any different than using a card and a POS machine, so that would be possible. We also need to make sure that blockchain tech is a lot better, because we are paying too much for transactions right now and it should be a lot easier to accept these payments without charging too much.
