The website says you've given away over 197,000 BTC (currently equivalent to about $1.4 billion). Likewise there are a total of 101 billion games played and almost 35 million members. That means on average, each user on the platform has earned 0.005 BTC.
Take into account that a few years ago the BTC price was much lower. Also the minimum and the amount that could be claimed and collected was much higher, so much more BTC was distributed earlier than now.
