Covid 19 actually proves that digital currencies such as cryptocurrency are superior to conventional currencies. Conventional money is so badly affected that it causes a bad economy.
People never think how bad is COVID-19 affecting the global market and not seeing it crashes somehow. But the good thing is that the crypto market doesn't have a losing chance to grow instead, we are seeing its huge improvement since the lockdown is implemented by many countries. This will lead into more adoption to crypto and that it also helps to open up the minds of the people who were sometimes doubtful towards Bitcoin.
Well, I don't see this will be a reason that conventional currency will die but I see that crypto is taking a huge part in surviving the hard situation we face now.
