No,  you do not want to buy those useless things because when you buy those, you do NOT gain any reward points.  What you do gain is more free sat bonus though,  it is 20x vs Mulitply which is only 4x.  However,  since reward points are more valuable than sats,  the choice is clear,  stay away from the lottery if you want reward points (which I do).

The question most people do not seem to understand is WHY reward points are more valuable.  So while the encashing is done on a 1 to 1 basis (1 Reward point == 1 satoshi),  what you forget is how you GOT those reward points.  You got them by playing in the Multiply game.  So they are essentially left overs from that.  But,  you dont not ALWAYS lose in the multiply game.  Sometimes you get lucky and reach the 30K sat level and then you drain the account as soon as it hits 30K.  This is why Reward points are so valuable.  They allow you to play multiply game with less risk.  Also dont forget that multiply game is NOT the only way you can gain them.  You can also gain them via a "+100 Reward Point Bonus" which costs 1200 satoshis as well as all the 2x, 3x, 4x, and 5x Reward weekends.  So,  because there are so many different ways to get Reward points,  that is why they are FAR more valuable than Lottery tickets OR satoshis.  The more ways you can get an asset,  the more "liquid" it is,  the more liquid an asset is,  the more it's worth.  Basic trading principles applied to Freebitco == winning strategy.
