If you buy the tokens of your company, will I have the right to vote or influence the work of the company?
I think that there is not as ICO works differently and you can earn well by selling tokens on the exchange or in other ways but the tokens are not shares
Token is more a measure of the company's success. The higher the price of a token on the exchange, the more popular and successful the project is. Although not always so. Sometimes good projects can be underestimated.
Usually, if the project is usefull and its popularity is growing, then its tokens are also needed for everybody and the price for them is growing. The main thing is that people see the benefits of the project and its usefulness.
