Well the fact that faucets are just a waste of time would make traders do it while watching the price of a certain coin to go or down. So maybe I rather suggest a dice or a minigame on it to make people not get bored while watching the certain coin.
Traders doesn't need that killing the boredom activity. Too much features aside from the main feature which is exchange, is like turning it to to the same face of Yobit. It will just take some additional bandwidth on the site although not that much, and it needs all factors that gambling games needed in order to have a fair system.
Majority of big and popular exchanges doesn't have that feature so that is not necessary.
