I would say it would be very difficult to create a new coin and get it to become huge. You would have to innovate beyond measure and would be expected to change too many things back to back in one blockchain and would have to have an amazing team that would do all their jobs perfectly and would have to spend a lot of money on marketing and community building. All of those all together is a very difficult task to handle and I wouldn't really expect it to be easy for anyone.
on the question of innovating Is something very difficult, in that I agree, but in this business world we have to know how to look at what someone is doing and be able to create something better than that person is doing and at that point most altcoins are not doing it, on the contrary they are only doing copy / paste and reducing the quality of existing projects
about blockchain, sometimes I keep thinking that scammers believe that blockchain is a magic stick that works miracles
about team, that's a big point. What I realized when I looked at many new altcoins Is that the person creates a project for example to create an application to improve the public transport network, but the people on the team never did a public transport business, after collecting money from the ICO and starting implementing the things they promised they are unable to deliver because they never did public transport business and the project dies
about marketing, this is another point that I disagree with as a current model, I don't think it's fair that someone comes up with just one idea and makes people on the forum disclose their altcoin and after 3 months that person who owns the project does not pay members of forum that made a lot of effort to publicize the project or pay a very low price because altcoin had a very low price. I think that each new project should pay in bitcoin to everyone who advertises the project and should put the funds in escrow.
about community is also another point that I disagree with the behavior of the new altcoins. when they want money from people they are active in the forum, but when these owners of altcoins already have money they leave the forum and only stay on twitter
