Actually first time when Bitcoin is created in this time it's not famous currency i think.It takes a lot of time to get something famous.Bitcoin popularity now spread around the world.

Interesting.. Satoshi Nakamoto is the original hodler, having left the bulk of his coins unmoved since day one.
The theoretical wealth of bitcoin’s pseudonymous creator is a hot topic, and one that the mainstream media are especially fond of pondering.
In recent weeks, bitcoin’s record highs have propelled Satoshi into the billionaire league, making him one of the world’s 50 richest people.
There’s another reason why Satoshi’s digital wealth is growing however: people keep sending him bitcoin.
The number of bitcoins owned by Satoshi Nakamoto is widely regarded as being 1,148,800, based on a detailed analysis that was published in 2013. Evidence shows that the bulk of the first 36,000 blocks was mined by one computer, which can only have been Satoshi. At the time, the reward per block was 50 BTC and of the 1,814,400 awarded, 63% was never spent, leaving Satoshi with a fortune of over 1.1 million BTC.

The bitcoin can be famous, surely through a fairly difficult obstacle to date. in the end bitcoin can later be advanced slowly.
with that we do not consider the bitcoin process is easy, even the bitcoin process is very complicated and takes a long time.

Still famous and it will be more popular day by day. Bitcoin is just awesome

bitcoin was not so popular before 2 years but after that it has got popular in every country because of its raising price

Still Famous ? are you kidding ?

Bitcoin is better now than few years ago...

For me, bitcoin is the origin, it is where all coins came from that is why its famous, another reason is that its volatile value, raising higher at a fast rate then receding value at the right pace for investors to buy their btc again. There are still enough BTC there that are getting mined so it increases its quantity in the circulation, getting higher and higher in value for investors. Lastly, as long as BTC is used by many and its value at its peak, It still be Famous.  

of course bitcoin is known and doesn't lose its popularity, because it now offers people the great opportunities

Bitcoin is indeed famous or rather very infamous to most financial analyst because they think that bitcoins act like a bubble, or has gone parabolic. Which got me thinking, are bitcoins too big to fail? It is really scary. But I do get why bitcoins are getting a lot of attention these days. It is because of its soaring price from $1000 to quickly $20,000 in a single year.

Bitcoin is making famous day by day all over the world. People are taking keen interest in this currency just because of the way it is increasing in value and making people are rich. Everyone is working hard in this world of competition to get a job which pays them off in the way they deserve but bitcoin has ended their quest for such jobs. People are now their own boss’s juts because of this mighty coin.
