Not in the near term. It will be a loong and difficult path to mass adoption but we'll get there.
Yes we'll get there, I think so too. I am not utterly convinced, we'll get there with bitcoin, though... Well, anyway, we'll see soon enough.
Well that is not so easy old chap! One a small percent of the entire population of the world uses cryptocurrency for different purposes and not the rest of the people who completely rely on fiat for running their lives. Access to the technology is not possible for all and still a whopping portion is left to avail the benefits.
Besides those who have access to it are somehow influenced by various agents to alter their investment pattern and this speculation of crypto replacing fiat is not realistic in near future.
