It takes 100 points to equal a dollar and if you scroll to the bottom of this page where it says "Answeree Rewards" you will see how much each activity is worth but before you can join the reward programme you must submit 250 points to admin for approval.
You should also note that you need to make 3000 points which is the minimum cash out rate of $30 by the 22nd December this year because the site is changing and the reward system will be different from the 1st January 2019. These changes are also set out in the Answeree Reward page so you need to decide whether you will be able to make the deadline in the time we have left.
Each answer is worth 10 points and must be 600 characters in length, questions are worth 1 point and you can write unlimited replies which are also worth 1 point. You should also bear in mind that there is a limit of 7 answers per day when calculating whether you will make the deadline.
