I wonder why haven't there come potential coins like ether. The only project that looked promising to me this year was bittorrent which was lauched on binance launchpad.
But even that is not going so well these days.
Is the world out of ideas or solutions?
I don't think this is true. You're just not doing the proper research. It's fair to say that 95%+ of current "projects" are vaporware.
If you want to make money on these types of things in a few years then look in to projects with actual viable products. How does this token/coin monetize what it's doing? How can it be adopted? What impact does it have? Is the adoption barrier low or unrealistically high?
Just think, what do you believe real people will actually be using? You can't tokenize every aspect of human life and expect it so succeed. Some things just don't need blockchain.
