Why bitcoins? For me it is an imcomplete question why I really don't understand what it would be or what would I say in this simple question but I know it is broadly to answer. Bitcoin because it is a cryptocurrency. It helps us in different things and it has advantages to many people. It has a greater and increasing value that makes very happy of every bitcoiner. Because bitcoin is a good way to invest and it is easier way to have a profitable investment. It is a big oppurtunity for us to have an extra income. It helps me in a way that I can provide my own money in an easier way. I can support my family needs as well as I can buy the things I want amd I enjoy doing bitcoin. I believe that bitcoin is the one that will make me to become a millionaire and also all the people who do bitcoin. Lasty I do bitcoin because It has no taxes for us and for every businessman.

I agree with your opinion that bitcoin is a kind of crypto system and payment system around the world which is a digital currency, let alone bitcoin is a coin that is often hunted by many people because in terms of price alone bitcoin very expensive.

I like Bitcoin because it has given me the opportunity to work. I'm getting a great  income and that's really nice. What is more, Bitcoin is known to be a digital decentralized currency. 

Aside from it bitcoin is the mother of all crypto currencies and bitcoin is the reigning world champion as of now with regards to it's value.
This is how the in demand bitcoin is therefore we can use bitcoin in different ways for us to gain profit.Either you are  planning in a long term plan or a short term one.

I think the purpose behind Bitcoin on the grounds that is a digital currency that have quality to withstand an abnormal state of protection and still can recapture it's quality to remember upward at whatever point there is a drop in it's cost. Additionally it have make an abnormal state in its core speculators which have demonstrate it is a decent venture source.

But the value of bitcoin is not fixed, if you invest 10bitcoin for a project equivalent to 100k $ but if the bitcoin decreases then the contractor will bear the risk that the bitcoin price dump.

Bitcoin means money, it help's a lot in our life.Not only that,it can also be communication via bitcoin, bitcoin is helping us in many way.Bitcoin's role in the world is immense..
