I don't support that each country will have its own cryptocurrency. Cryptocurrency in that case will become cheap and will not reflect or represent the real idea behind cryptocurrency. If every country will create their own cryptocurrency, the idea of a global currency disappears. The idea of a free currency that is beyond the control, manipulation, valuation, and ownership of a single country will die. The idea that cryptocurrency is open and free for all, not owned in any way, will end.
Really? Let us try to take a careful look at the cryptocurrency world right at this moment. Let us not speculate on what is to come because that is beyond certainty. We cannot be sure if the future is really the one that we think of. Let us look at today. People, companies, institutions, etc are now creating their own cryptocurrencies. We have several thousands of them today. Now, do you consider it a successful condition? It somehow cheapened the quality of cryptocurrencies. It has proven that the creation of crypto is handy. It has proven also that there is possible money in it. But has it really proven that it greatly promotes adoption? No. It has even eroded the trust of so many people. It has even earned the ire of so many true crypto supporters. We are full of cryptocurrencies right now. Most of them are shitcoins already. Does the whole market cap grow because of them or their sheer number? Again, no.
