The question is vague. What do you mean by future—exactly how many months, years, or altogether future? I am taking this as a general question, so the future of crypto currency will definitely be the one that has the power to pave the new path for the world economy. That will happen now, and we are part of that change. I can't predict how those changes will be, and I don't know. But I can assure you one thing: when the world economy accepts crypto currency trading for real, it will be a huge technological revolution. And I don't know when it will happen, sooner or later, but prepare for it.
Every one had their own definition for the future,if the person is old age person.The few month will be their future,to the young people working in the factories.The early 50 or 60’s are the future for them.But the answer is bitcoin will survive for the period of next 3-4 decades based on the some experienced economic people.Now the world economy was started to accept the bitcoin as their assets,this was the big news for the crypto currency holding people.The trading of cryptocurrency itself consider as the real job.
