I have seen that many currencies are created based on an idea, that they intend to be used for something, even though at present they are useless, they are based on the hope of being used. I hallucinate seeing how some collect millions in the ICOs only promising that they will be adopted en masse, only selling an idea that has not yet been started or developed.
This is happening also not just in cryptoworld. There are those business start-ups that are selling (but I guess"sharing" is the best word) their idea in order to raise funds for them to use in realizing those ideas into a tangible one. The potential of the idea may correspond to how much funds can be raised. I think that should how a certain business start esp those who don't have funds from the very beginning. Not really different in cryptoworld, right?
I believe that for the creation of a new currency to make sense, it has to respond to a real need for the exchange of goods and services,
I can't disagree on this. But personally, I can see some really good projects that could somehow be useful in the future especially in fintech industries. We just need to give them time to do what they have promised in their roadmaps though I am aware that until now, there is no or only very few out of thousands of projects that has fulfilled their promises and is now in a full-swing.
