A user receives 5 jackpot points when he joins SupraBitcoin for the first time with a confirmed account, or 10 jackpot points by following an affiliate link.
He also receives 1 jackpot point when he reaches the end of the grids with a real bet.
That very hard to get end of the grid. So, people will get all of the current jackpot right. Not divided to 2 people or more.

Indeed. A reward of one point jackpot when a user reaches the end of the grid was not enough. I did not realize that until several players tried to achieve.
From now on a player wins 3 jackpot points as a reward, whatever the amount of his bet with real money.
Players who have won jackpots point in the past received a number of points equal to what they would have obtained with the actual reward.
