For the exchanges, day traders are the cash cows because it is the day traders who keeps the volume pumping in and out of the exchanges on a second by second basis. Day traders are, BY DEFINITION, the contributors of the market.
On the other end of the scale, you have the traders that employ long-term strategies. These traders are extractors of trading volume
They are content to be positioned in a coin for the long haul. They remain positioned as hundreds of day traders contribute to pushing the price of their coin higher with each passing day
then, with the passing of 30 days, the value of their position will have increased by, AT-THE-VERY-MINIUM, 100%.
