Confirm for gems

Hello. 

Many of us lost… all of us… has already lost gems typing on the wrong button. 

There is confirms when we win 1 gem. Why there is no confirm when we spend 10000 gems ( for the 8th slot for exemple)? 

That’s completely unfair. 

I ask the question into a little groupe un Line and everybody is agree with me: 

put a confirm before spending gems
