give out bonuses in the form of 100 doge 
Nice try to attract people especially those who love free money, but yeah it is good as many people will try to claim it and maybe play for a while with the free coins but do not expect that they will spend their own money on your site. I'll see how long you'll be able to offer free coins as I doubt that you have enough bankroll to cover such free promotion for long time.
I guess he can not cover up such huge amount needed And may end up ignoring all possible players because he can not afford to give them all their needs, And who doesn't want free money but that is the only reason they are entering his site, And as I see his site there are not much content in it, It got simple UI or interface there is not much detail in it, So other players would really think of it as a fraud so clean up is the right thing to do.
