You will find huge amount of gambling site announcements on this forum. It mentions what amount of bonus they are giving. So you can target them. But many sites can lure you in different ways, so before using any site, you must do a good analysis on them and then use it. But I've been playing blackjack for a long time at the stake site here and have seen them give away $75k/$150k Raffles every week.  I won't say you use this site but whatever site you use do your research well first
