you can take advantage of the offer, and unless variance goes against you, you can make a profit (as I said it's not just a simple 1%, a 1% edge in your favor compounds over multiple bets, just like a 1% edge against you can sometimes wipe you out in a single session).
As long as there is someone who can show the result, maybe based on how much they bet + result.
That's would be great, cause still boosting the RTP not really effecting you at the time you're played during your gameplay. Still need a millions bets and more to see the RTP are going favor to your side.
Just my two cent, I hope no offends you.
