Dividends are often falsely offered by many crypto currencies.
Usually currencies by themselves are promising new coins as a result of PoS mining and most of them are scamcoins, it is not dividends. Dividends is a someone's share of profit in the company. I can't understand how a currency can give a profit in the same currency without any emission.
It seems like the project is offering dividends from something without a clear explanation about the source of dividends.
