2) Spinning it together will increase the odds of hitting better rewards.
This is not true. It doesn't make any difference whether you play 100 spins at the same time or you play 1 spin daily for 100 days.
Take note that every time you play the wheel of fortune, the outcome is determined through some mathematical calculations and they are completely independent from each other.
Yeah right because before there was someone who had rotated his entire collection of WOF spins around more than 2k WOF spins even it wasn't high value maybe due to the high price of bitcoin making free btc earnings from WOF not so much no more than 1 mBTC so it's actually the same want to play how much and save at any time it's back to luck on his account because the prize of this spin depends on it.
It is possible that someone who has 1 WOF free every day can get 1 GT or the main prize, because no one knows whose side luck is on, no one can predict it even though it is due to mathematical calculations no one knows who will get the main prize , in my opinion, the right decision is to play all the WOF rounds when you get it, let alone see the current bitcoin price which has increased, because when the price increases, the bitcoin prize will also decrease.
