I'm the same. Registered three years ago just before making this bitcointalk account and still haven't won anything. Even winning the smallest prize there would be quite a nice change.
Hopefully the build up for both of us is that we're going to win the top prize instead at some point.
Same with me, no luck in FreeBitco.in lottery. I don't remember when I registered (and I couldn't find the info in my profile) but it's been quite some time. I'm not sure I have the right to complain though. I've spent 0.00009754 BTC on lottery tickets during the whole time. I even spent more on jackpots, 0.00025109 BTC, which I haven't hit either.
Nevertheless I enjoy visiting the site because it's free and it's fast, and there's always a chance to win $200 in freerolls or even much more in the lottery.
You are 100% correct, you do not have the right to complain about NOT winning the lottery, with a combined total of 9754
tickets bought for the lottery. Have you worked out what your odds are with 9754 tickets on a Lottery that sells over
1,000,000,000 per week? Like you said, just enjoy the site and write the experience off as entertainment and you never
know, one day might just be your lucky day.
