Everyone is starting to believe that bitcoin is the future worldwide payment system. 
I dont really know much about it.  Can you explain it more to me?
It is a digital currency it works without a bank or administrator I signed up with a stock bond that uses bitcoin only.
Ok interesting.  So is like a modern day stocks and shares?
Yes that is one of the ideas behind bitcoin it was also created for products and services as well.
What kind of services and products do they offer?
The main source is work system mining and it is also for digital structure share transactions. 
Its quite confusing to me.  Are there other companies out there that are the same as bitcoin?
Not everyone is using it I'm apart of a face book group that teaches information on bitcoin it is very confusing I am trying to still get the ropes myself but they believe this is the face of the US in a few years because transactions are basically verified by network nodes from cryptography.
