You have changed your tune. You said the illegal lottery paid 10000 for a 80 baht investment (the government lottery price that gives you many chances, not just the 2 numbers), i.e. 125 to1 for a 100 to1 chance.
You obviously have your numbers wrong, that is why the bookies pay only 50-60 to 1 for a 100 to 1 chance. They have to make money but no serious punter would take that return.
