For the first time, the world's bitcoin has topped $1 billion. This is a remarkable achievement for a purely virtual currency without the support of a central bank or other authority. But this is temporary: we are experiencing a bitcoin bubble, and the bursting of the bubble is only a matter of time. (this is a quote from the media in 2013.)
People have been saying that BTC is a bubble, it will break up very quickly, it's been five years, BTC is still very expensive ($10,000),
There's going to be a lot of people who don't believe in BTC, think it's a bubble, but I tell you that whether you believe in BTC or not, it's still here, BTC is changing the world.
Bitcoin is a boon for the mankind. Bitcoin is a very innovative concept and it has that much potential to be very great that and it has helped millions of people to earn their livelihood and get employment. In our world there are millions of people who are enough educated to operate computer and internet at least but they are not even able to earn their livelihood, for them bitcoin is a life saving drug, and bitcoin is the only job that has helped them to get their livelihood, so if we have faith in bitcoin then bitcoin can take you to the the heights and moreover you could be the next bitcoin billionaire too, so if bitcoin is a bubble then I am also sure for one thing that this bubble is never going to burst.
