Don’t know weather bitcoin will be an international currency within this 2-4 year but it will sure be recognized all over the world within a decade. Some people have given their all time in it so they can earn more. People are also using it for the online payment and where ever bitcoin is used they use it and holding them for long time will always give you a good profit as its increasing publicity and market !

Yeah that i can also say that bitcoin gives us opportunity to earn money easier than in real life because on internet there are many opportunity to grab to earn a lot of money like doing trading (bitcoin,altcoin and other kind of trading) investment (HYIP,Cloudmining etc.) and many more.

People use Bitcoin because, for certain transactions, it’s cheaper and better than the alternatives. when using Bitcoin might sense. like these way.

people used to live in Germany, and occasionally they will ask friends there to send them things they can’t buy in the U.S. In the past, they would use Western Union to wire them money for the purchases. But if they wanted to send $100, they was slapped with a minimum fee of $5 (going as high as $25, depending on the payment method and location), not to mention Western Union’s often less-than-favorable exchange rate, which further added to the cost.

Today, people use Bitcoin to send them money. With 1 percent conversion fees on either side, that adds up to about $2 in fees for a $100 purchase.  The best part is, instead of taking three to five days, my transaction is processed in only about 10 minutes.

perhaps Bitcoin helps tackle the problem not only by lowering the transaction fee, but also by splitting it between the customer and the merchant. For merchants, that means dropping their fee to 1 percent and improving their bottom line. For consumers, it means faster payments than cash and not having to hunt for your bank’s nearest ATM.

bitcoin definitely has a good future. I think its been already very late for the peoples who didn't started bitcoin yet and those peoples are so unlucky that they don't even know about bitcoin yet.
but I also think that if some one need to go with the time and the technology then he should start bitcoin if he is not using bitcoin yet.
the world is being digital and bitcoin will be an necessary need fro future..

It's true, Bitcoin have lots of benefits in it.  But there are some drawbacks too.  Anyway for benefits, people will have currency and investment in one package.  The high volatility of it make it so.  The fast transaction is good.  The ease of using it gives an advantage too.  I think the benefits overshadowed the drawbacks of BTC.  So people must use Bitcoin in my opinion.

Disagree. No such thing as late comers in the world of bitcoin. How come you guys are expecting a mass adoption but have a thinking that it's already too late for newcomers. What is the essence now?

It is our duty that we spread the technology of bitcoin among all of our friends and our family members, with that bitcoin will become an established currency sooner.

Bitcoins is the currency of future. It is accessible for all the people around the world and it's easy to participate. Bitcoin can be ever reliable to do to financial transactions. Bitcoin is becoming very essential and it's popularity is also increasing among people. Financial transactions are done directly done without the middleman that must be a revolution of mandkind.

That is right. Also bitcoin is deflationary. So if I hold it for long time, my value will not decrease, not like the  US dollar.
