As the title says that if you want to increase the price of bitcoin then promote it everywhere around you. As if you will promote it and will discuss about bitcoin with your friends and family and your other relatives then they will also invest their money in bitcoin and the name of bitcoin may reach to a group of people who will have a high amount to invest in bitcoin which will increase the demand of it than its supply.
I am saying it because a few days ago I heard from a person that he discussed about bitcoin with a friend and after that his friend felt interest in that coin and he said that he has a total of $60000 income per day from his business and when he will fully learn about bitcoin then he will invest all of them in bitcoin each day instead of depositing them in his bank account. If people like that will get awareness about bitcoin then once again the price will start to rise.
I agree with your statement about the promotion of Bitcoin. It is true that we can increase of Bitcoin by promoting it so that investors will give it a try when they've seen the potential income from Bitcoin. As for your statement that we will be involving our friends and relatives is kinda hard, the reason why is that people who just know you trust you even they don't really know how Blockchain Technology works. Then when they don't get what they expected and failed to be rich instantly, they can easily put the blame on you.
