If it was dividend on a stock market it should be around 30 years roi but lets say 20 years because of crypto volatility.
That calculation brings a token value around 3.5$ right now. So i really wonder what will be the price after listed on exchanges.
This is a very small profitability for the cryptocurrency market, where with successful trading you can earn 5-10% per day. I would not risk for such a percentage of earnings as these tokens.
