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?
Crypto currency is all about speculation and the people believes that the price of a certain coins will get expensive once the real product will be available and functioning. The higher the demand makes the coin become valuable as people has a tendency of FOMO then they buy and hold the coin.
