We could learn a lot if we are just going to search bitcoin or cryptocurrency in search field.

Recently bitcoin has become the hottest buzz word on internet. Every single day i use to read whole lot of posts about bitcoin and also used to read how some one has forecaster that in coming years bitcoin is going to touch $10000 and the person who have forecaster this is also running a version of bitcoin i am not pretty family with the terminology but yes every single virtual currency have its own benefit but at the end how this is possible that a virtual currency is making people king of their own world but at the same time many country are seeing hard time to sustain their economy.

This all news and gossip about bitcoin and cryptocurrency has raised whole lot of question in mind and that is why some question arises, How to proceed with these cryptocurrency ...

3- What would be impact on bitcoin if some of world's largest companies would start holding their money in form of virtual money
4- As a naive user how one should start with these cryptocurrency.
5- What if by mistake someone is going to share his/her private key with others
6- Final question, how we could keep ourselves updated with new trends in cryptocurrency
