bitcoin is the future currency and we can start by saving it from now on because bitcoin is now increasingly loved by the people of the world especially the developers have got a lot of solutions in promoting bitcoin everywhere so that this is one of the opportunities for all of us who use bitcoin this.
Even we say that bitcoin is the future currency its hard to predict if this could really happen. There are chance that bitcoin will be gone but I do not want to happen it. Bitcoin is already spread in all countries so aside from promoting it we need to implement it as legal currency.
