If only you were there at the very start when the payouts were $2-$4 for each winner. That was the very beginning though and didn't last for very long. Back the there were only about three players who won pretty much all the games but they made a few hundred in those couple of weeks. Not bad for playing a game. It's a pity it's gone, even just for the fun side of it but as you said there are so many other projects that you can get involved in and some that you can earn a bit too.
My baby at the moment is the engagement and curation league. It charts accounts over a variety of engagement categories and has a weekly league for it. There are some prizes for the best participants and you tend to earn a bit while competing too. I've noticed the difference since i joined it and have seen my account grow a lot more rapidly than it ever had before.
