To achieve alpha points, increase transaction volume. 15 points a day for 15 days means 15*15=225 points, reaching 225 points. If you get two within 15 days, you still have 195 points left, which is basically not a problem, and you might even get three. At 16 points a day, you can get 3-4. At 17 points a day, you can get 5-6. It's not very good to just wait for others to give it to you for free.
