The main reason is that there is no reason for 99.9% of cryptocurrencies to succeed. Most altcoins will eventually have a null value because no one will use them anymore. Few people will dispute it. But a financial failure does not mean that they will have been useless. We need at least dozens of crypto-currencies to test different technologies and applications. At present, different altcoins are developing different approaches to anonymous payments, smart contracts, peer-to-peer file storage and decentralized markets. It will take years to be advanced enough to effectively combine all these applications on one platform. Market consolidation takes time, but we believe that cryptocurrency is one of the most efficient marketplaces on the market.
