what is a token? and how could I use it?
he token is actually a new term referring to a value unit issued by a private entity. Although tokens have many similarities to bitcoins, they are more important than currency, because they can be used in a wider range of applications. Also virtually all tokens are based on the Blockchain Ethereum protocol, which according to experts is more complete than bitcoin blockade.
In other words, a token is a unit of value that an organization creates to manage its business model independently to enable users to interact with its products, and to facilitate the distribution and sharing of prizes and benefits with all interested parties.
in this sense the token of the ethereum platform for example will always have a value lower than that of the ethereum if I understand well
Not really. You are confusing the whole idea of creating tokens. Its just entity representative and its real value depends on versatile factors. Like, how much investment is being made into it, what is the total market cap for that token, development of that token issuing project. All these, if inline with projects roadmaps (future plans) then people see it as opportunity to gain the profits by investing into its early stage where the prices are very low. As they keep on investing, its market cap grows and thus its value starts rising.
Now this value can keep on increasing all the time no matter what is the value of ETH itself.
For instance BCH is altcoin whose price is $ 1398 at the current time. Its all about the facts that i mentioned above who decides the prices.
ETH is getting its value in the similar manner,( how much its being utilised!)
