i think its okay, if world don't have bitcoin, why? let me tell you, in 21th century, right now, we can see there are many electronic payment in addition to bitcoin, we can see paypal, visa, contactless payment, NFC payment. and i think its the future to besides bitcoin. maybe, if bitcoin is doesn't exist in the world, i think its right now and we can live with other electronic payment
In the field of online payments, we have so many alternatives, even better than bitcoin in many factors, so even without bitcoin, the world won't have a problem with payments but those in the investment sector fear more if the world does not have bitcoin because they are forced to return their happy lives to return to a normal past and may be difficult in the methods of making money. Bitcoin is even major financial source for many people, it is hard to think what problems will occur if Bitcoin disappear in the near future
