I dont see a single improvement .. as long as Cryptos depend on Fiatmoney they will just serve the system instead of replacing it which was the intention behind the first Bitcoin in 2009 ... the seed of failure was already planted into the BTC-programm .. as long as the value of a Crypto depends on Fiat it cannot become a replacement .. so why Cryptos if they do not build a new world but just become some "assets" for (fiat) speculations ?
