We can encourage them by let them experiment with it, let them test it and than they will soon or later gonna sue it for sure.
No it's not right to let them experiment because businessman have no ide what bitcoins are but you can explain them instead of let them experiment they also need a basic explaination.
Yes businessmen don't have time for experimentation when it comes to their business. They won't even waste their time for nonsense thing, let's just be real to them and explain everything with it, possibilities, problems just too good for them so that we can encourage them easily and in a nice way. Because once they will find it out that you are lying to them, you'll dead.
Most business are not in the market for innovation they are there to make money and as such they will try trusted and proven methods, bitcoin is a great innovation but Im sure many businessmen will not consider it for now simply because it is too new.
