This is the first time I heard "loss bonus", are you referring to lossback where players get few percent of what they have lost back? If it is something like this, as small gamblers who will never lost big amount but I may wager big, I will prefer to see rakeback which is something count based on how much I wager. For sure there are some other players who may prefer to get lossback, so it is your own right to choose which one to have. Having both will be better . Coming to deposit bonus which is usually come with high wagering requirement, I dont think it is an attractive offer but again we can deny the fact that there are some players who like this type of bonus too.
