The win chance shown in lottery section of freebitco website is calculated wrong. The real win chance is bigger than what is shown.
Now the win chance shown is equal to [(your tickets/total tickets)*100%]*10. It's wrong.
The real win chance is bigger. Because the person who wins the first prize will no longer have the chance to win the second to tenth prize, and all his tickets are removed when next winners are being determined.
Some people like you think lottery is something very easy to win, we are talking about odds that many people don't even bet on dice games, it is literally less than 0.1% chance most of the time, of course you will lose every single time because it is lottery and there are literally millions of tickets every single week, so you do not have a chance to win it 99.9%+ of the time every single week, don't look at it like dice players do where they think after 17 losses it must be a win on 18th because every single bet is a new one and every single lottery is a new one, you will end up losing every single time.
A guy with 1 ticket technically has the same chance of winning the big bet as someone who has 1 million tickets, only 1 ticket will win an you do increase the chance by having more tickets but in the end there are so many combined that you are just another ticket holder among many.
This is how I see freebitcoin for now, I admit it that they really having huge edge right now but it does not mean you will lose money here. Instead of losing I want to say that they give us benefits to get everything, from the faucet which you can it free. Chance to take part into weekly lottery system which is free too and the last one is their biggest prize currently, that is lambo, which you can get it free. So let me asking you which part does cost you money?
