If you say is succesfull or not i think its success but not yet successfull, its needed more adoption in real case and real use, this revolution on financial technology need more time and effort not only hype and bubble on cryptocurrency.
You're correct, the reasons why global adoption has not taken place is the fear of hype and bubbles which has been in display on the side of cryptocurrency. This has scared many other potentials projects from integrating their projects into the technology, although many are yet to accept the facts that this technology is transparency driving and can give more accurate profile to its bearers. In my judgement, this technology is a success in transit, let's wait for global explosion.
