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.
First tr to promote the concept of bitcoin in your local area to everyone and make sure that now they will adopt bitcoin easily without any hurdle so when you will then start a local business and people will start using your service then other local businesses will also use bitcoin for themselves.
It is not going to be an easy job to promote the concept of bitcoin especially in your local town. Because most of the people there doesn't even know what bitcoin is, if there are maybe not even going to reach 1% of the total population to your local town. Hmm, but maybe if you will conduct some seminars for the business owners and tries to educate them with bitcoin without something you are asking for them in return, then maybe they will encouraged to use and adopt bitcoin.
It will take a lot of time and aggressive advertising and crowdsale to get that 1% to at least 30% of population who accept and use bitcoin. In countries where people have never heard of bitcoin, it is extremely difficult to make them understand and accept the integrity and security of the coin let alone try transacting on it.
I dont think any company or team will be willing to invest in such an advertisement because they may not just ROI that amount and end up as laughing stock on the stage with people screaming "scam/ponzi" at them.
