I still confused about what makes token become expensive. Except for supply-demand, what else which caused some token like erc20 become valuable? I look at about how to create ethereum token and I think almost all of them have the same quality, and security. So what's the answer? what make them so valuable?
on the other hand that really makes altcoin very valuable is they have and offer a real product or service, and not just a theory on a paper. besides the roadmap also gives a broad overview of how the altcoin will be developed
