I believe in a lot of things, especially those which give me a lot of benefits. Bitcoin happens to be one of those things that doesn't have to be physical or tangible in order for me to believe. I have been making some good amount on the side because of bitcoin and I hope to earn more in the future with bitcoin becoming more prominent in the digital world.
That's right people who are earning good money from it will surely believe in it and have faith in it as its increasing their monthly income and if they keep on working on it then they can earn much more in future.
