The public are afraid that when cryptocurrency comes to stay or when cryptocurrency is fully implemented that most companies will not have work again and some countries may go into recession. That's the public perception. This is not true, why? Because whether there is cryptocurrency or not people are going to participate in the activities of financial transactions. To me, the true of the matter is that some persons have failed to understand the use cases of blockchain and which area they should focus on and this is the reason for all these fear.
