How i convince myself and my friends about bitcoin is by looking at the value of it. As you can see you see very much money and that is because a lot of people believe and invest in bitcoin that makes the value go so high. And i think that that is a good way to convince people about bitcoin.
I think before you do convincing other people in bitcoin is you have a knowledgable in every corner of bitcoin. But before you do it make it sure that the first person that you convince is your family and your friends because they are one who truly listen of whats your agenda that makes them get into interesting. Tell them about investing bitcoin is the most profitable than other business online.
