I would say that when a person takes all the Steem Dollars or when he tries by any means to get the voices of whales and dolphins, he eats one Marshmallow candy. When man focuses on communication within the community, patiently creates interesting and useful content and investing money in Steem Power, he is like the child who endures. He will get two Marshmallow candies in the end and will become more successful than the previous one.
So yes, here is a psychological experiment like that one with marshmallows :)
