Is the 10k deal worth?
1 guarantee random rainbow worth 5000
160 rainbow coin worth around 2400
rainbow skill worth free
rainbow slot worth 3000
40 salt stone worth around 3000+ little bit

For me 10k is too much.
If I have more free nice pull I'll go for it 100%. As a thanks for dev kindness.
But since the game keep throwing salt to me so... no.
