How to explain something that you can collect and put in your basket? And later you can sell it. All these things are digital. So yes, you can have a digital basket or a digital pocket. They do not exist in the real world. But they are useful to the real world and it is the only way we created where the whole world knows you are the owner of this thing. Nobody can steal from you or can replicate this object. It is only yours. And you can prove it. You can show it to the world if you want it. And if you are tired of it, well then, you can transfer, donate, sell it. It’s up to you. Having this object in your basket or on your ‘wardrobe’ is also a way to demonstrate your support for something. You bought them because you wanted to sponsor something. It is a little bit different from donating. But also you show the world that you really care about it. Stay together, come along with us. We will start to mention some technical terms. Slowly, please.
