We've all seen this phrase before: that the government and/or banks will more likely to create their own cryptocurrency, but what are the odds that they really will? How can we be sure that these two sectors will create their own coins eventually and will it even change the game if they do? If they did, will it not threaten bitcoins and altcoins because the common people who haven't heard of bitcoin before might choose to use these bank/government-created coins instead? Do we really need more coins?
Over time, governments will certainly create their own centralized cryptocurrency. Recently there was news that the central banks of 15 states, including China, Canada, Sweden, decided to release their own cryptocurrency. If we are confident in the advantages of decentralized cryptocurrency, then we have nothing to fear. Let them create, experiment. I see nothing wrong with that. Centralized coins will only attract people's attention to cryptocurrency in general and increase its confidence in it. Indeed, in this case, the state itself will create and use a cryptocurrency.
