Digital currencies made by banks (Fiat) and Bitcoin (purely cryptocurrency) These are two distinct things that are obviously different though both digital assets and blockchain systems use. In my opinion although as powerful as any digital currency made by the bank with all its legality still will not be able to rival Bitcoin even though the price for example Bitcoin is under Fiat. Why can the original nature of the altcoin in particular this bitcoin is a different an anonymous with Fiat which there is required original data and all transactions can be recorded, both the sender and the receiving, although in Bitcoins have a fixed ledger is not Benchmark. And another important thing is that Bitcoin has already been born first in the digital market, Bitcoin is formed from a digitally and high tech code, while the Fiat is derived from the design which mimics the Bitcoin. And I think Bitcoin and other altcoins can not be replaced by digital assets that are made by banks. Indeed a product must have a minus plus its, I assume that the digital asset created by the bank will certainly not be as perfect bitcoin.
