I am exchanging my RP's for sats whenever I hit 100k! There's no point in keeping them I guess, we don't get anything from that, which is not the case with holding BTC or FUN, we have interest on BTC and WoF from FUN and higher interest on BTC!
Nice win Uneng! Recently I spinned +1200 spins and I got similar amounts of RP and lottery tickets as you, I got more satoshis +35k! Now I am close to 200 spins, I am getting 7 spins daily... and probably in some months that will rise to 10! This time I plan to save a lot more than the last time!
That is kind of what they want you to do as well, not like they are aiming people to spend their rewards. I am guessing that it would be one of the first things they would remove if they ever removed anything, just give people cash and they would be happier. I have zero information if they have anyone spending any other way, but I am willing to bet all my account on the fact that majority of the money would go towards encashing it for sure.
It's a great website, best in their field, combining faucet to a casino and then making it great in both aspects is hard and they are getting paid a ton thanks to this, they are making so much money and they deserve every cent of it, but reward part is definitely the worst part.
