I have to be honest that BFG promotions are not interesting e.g. olympic spin i watch this spin almost all users won 0.5 BFG or 0.02 BSW never seen someone win more than that even though I purposely took the time to watch the live spin for about 20 minutes. I guess the chance of winning is 1:10000
I tend to agree with you. Last spin wheel was more interesting as the minimum you could win was 3 BFG so a lot higher than this time. This wheel has the biggest prize till date (3BTC) but I don't think anybody won it yet.
Even if it's 100 BFG still unattractive IMO to get 1 spin the player must make a wager of around $130 ( 0.003 BTC ) while there is a risk of losing there
Playing with the aim of getting spins is really not worth it unless they play as normal and spins are a bonus it can be excluded
