none of those alts solve the fundamental problems that bitcoin has so why whould i want to get on any other alt but hold btc?
this guys claims to have the be all end all of cryptos solving every posible problem seen in bitcoin and every other alt, i dont believe it. why should I anyway?
There are solution that exists, in the things I posted from e lang, they already offert solution to have trust less decentralized network with crypto and there is no blockchain or pow/pos. They are making à system of decentralized e cash with it.
In theory the solutions exists, but the system with pow/pos is still the simplest, anyone can install and run a node relatively easily and the model of security is simpler in blockchain, but truly trustless decentralized system are already being worked on. And the theory is already there and according to them their code has already been audited and reviewed by independant groups.
