Tell me when will the first dividends be paid to the owners of the tokens?
Goldea plans to pay dividends each quarter after first financial results, doesn't it? So, earlier than Q1 investors shouldn't wait it. Tokens buyback is planned in Q4 2018, so somewhere in this interval.
Yes, but if you want, you can sell tokens on the crypto exchange.
Adding a token to the listing of crypto-exchange is planned one month after the completion of the ICO
