Even with the efforts done by the inventor Satoshi Nakamoto and the people who supported bitcoin around the world, still these guy from EY says there was no practical use for it and the deflationary model can only give damage to the global economy. On my thinking this isn't the case if this guy could only see how good the invention was. For me he was just talking non sense. Something that should not be entertained. Imagine how many lives have been saved by bitcoin in my locality. One was able to pay hospitalization, the other have been able to buy for him a house and lot, others have been able to buy a car to get to his job early, and so many other things.. See how people even made bitcoin atms and for just a simple reasoning bitcoin becomes useless and damaging? I think this guy has to wake up...
Yes, the other non Austrian schools of economy, fear deflation and its practically impossible for them to reason a life without inflation. Thus come with outrageous claims like that, when its the exact opposite. Deflation will move the economy from bubbles and crashes to stable and steady growth not based on debt but on savings.
The only thing damaging the global economy are the endless cycles this debt and inflation keeps producing, and fractional reserve banking. All of that must go, and bitcoin is fitting that void, with or without the naysayers.
