Yeah, I once tried the same thing as well before and I have to say that the result wasn't that great. I do not mean like it wasn't "great" as in it was worse, it's basically same as doing it Daily, just a regular result. This means that, you could do it once a day, or you could do it as long as you can, I don't know how long can someone collect it but lets assume like a full year and not touch it and do it later, the combined result of that would not be too different from the daily one and that's why I think it is a useless thing to keep collecting them.
I have seen some people win some, so I wanted to do the same thing, and it's true that when you do it all together the end result "looks" bigger but the reality is that we are talking about a situation which is combined results of daily just looking together. So I believe I will not do it again, unless I feel like I am too lazy, then I may collect a few and not do it and then do it when I feel ready about it.
Yes, there is no difference in that regard. Moreover, accumulating a huge number of WoF spins can sometimes be disadvantageous because the base rewards can significantly decrease while a user accumulates a few thousand spins.
p.s.
By the way, I noticed that the support account isn't active recently. Even though CSFBC was online today, he/she hasn't communicated with users in this thread for the last two weeks.
