Which blockchain is the most decentralized? Experts answer

Here’s what emerging tech representatives think about the decentralized nature of blockchain technology and which network is the most decentralized.

why do we need to use Asymmetric cryptography if diffie hellman solves the key exchange problem of symmetric cryptography

i am new to cryptography and i cant get my head around this issue: if symmetric cryptography is faster then asymmetric and given that diffie hellman key exchange algorithm will allow you to exchange keys safely why bother using Asymmetric cryptography if i can exchange symmetric keys safely ?
