I didn't understand well what you said. But a bitcoin success business are the casinos. Some of them are allowing only bitcoins and they are making nice profit letting players gamble anonymously, good for who lives in countries where gambling is forbidden.
But to make a business be successful you need to be a professional, need to be dedicated to your site, service, only this way you will achieve your goal.
of course there is a serious and huge profit when your business is an online casino.. thus this still need a lot of knowledge and analytical aspect before you do business like this. but if you have business or a store which you plans to accept bitcoin then it may or may not give you a huge profit though. as what the majority said, there are a lot of factors to consider. one of which is the number of people in your area who knows bitcoin. if there is just small number of people then it may not give you a huge one. but if the number is big then this will give you huge profit too..
