The new exchange rp to wof ticket feature is quite thoughtful but it's too much of a gamble. Rp is the most valuable thing on freebitco and spending it to
1. Reduce free roll percentage
2. Have typically 1 out of 3 chance of converting the rpto SATs with the other chance either being a refund or nothing in the form of lottery.
3. The result from number 1 would inevitably lead to a reduction in the value of free btc bonus which is currently the most profitable use of rp.
 
All In the name of gambling for Max rewards which have an approx 0.1% chance of getting if not less than.
It'd be nice from a gambling perspective in more ways than one, otherwise it's not really a logical choice for spending valuable rps.
