Has anyone won anything in TrueFlip and other online bitcoin lotteries?

Am checking out Trueflip: https://trueflip.io/?referral=b594955d1a904f16aa1bba34a8a59ffa&123 for two reasons:

1. whether I actually have good chances of winning the lottery
2. whether it makes good investment to participate in their current ICO where you earn a portion of all ticket sales.

What are your experiences? Thoughts?
