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?
So what do you think makes a valuable stock? It's just a promissory note issued by the business owner. Altcoin, too, was developed in the form of stock and was developed on computer operating systems. These are the cryptographic coin promised by the developers.
