I mean most these ICOs are not even original ...
Adult dating, real estate, gambling, etc etc ...
Really there is nothing new to the table, so what is it about ?
How much you spend on marketing ?
I think you should consider it as the power of blockchain, I personally consider it as the fact that a lot of organizations are trying to explore their products on blockchain, new ICOs launch every week now. A lot of products currently built on blockchain, with new ones launching everyweek, from agriculture or real estate like you mentioned. It is the quality of the product and the development team that will determine the value on the market, marketing comes later but its essential.
