The truth of the matter is this global pandemic is really changing lives and changing nations. Things that we gave little attention to like regular washing of hand, the use of sanitizers and social distancing is now a must. Some of our leaders are now building huge facilities to curb down the situation. The most important thing is when everything calms down the world is going to view the digital currency in a different spectacle which cryptocurency is going to be a great beneficiary.
