It was back in 2011 I think when I first heard about Bitcoin. And when I first heard about it I thought it was a scam and it will fail.
And back in those days, there were a lot of such things poping up, it was all new and no one trusted anyone.
So I never ventured into mining Bitcoin, and back in those days not many people thought that bitcoin would be such a huge thing.
Even today people fear bitcoin and wonder when it will crash.
As of now, Bitcoin is becoming something like the Berkshire Hathaway of the internet business. No matter how much you invest you end up earning some reward or some good ROI.
