Its indeed very hard to let people believe in the bitcoin
Open yourself a shop, and show, how it work, positively.
For a local business, you will find 1 from 100.000 costumers that will pay in bitcoin.
Online things can be more easy but local is almost impossible.
Though it is not impossible but we can surely call it hard to promote bitcoin in our local areas because the people around us have never heard of something like this where your money is kept on internet and you just can use them by internet but not like using paper money, so it would probably be quite hard to get customers for this at first.
Where I live for an example, very few people heared about Bitcoins. But they aren't interested on it anyway, they will say it's a hard method to earn money, or that it's a fraudulent method to earn, bla bla bla... So, I just go by myself and don't lose much time with others. Some people are living on old days yet, they don't want to see the real benefits the internet is promoting to us with BTCs.
I agree its the new way to gain profit and make your company very popular these days, I really think its a hole in the market this days.
