I do not agree that

"In the cryptocurrency environment, anonymity is one of the basic foundations of the distributed world." 

Blockchains such as bitcoin and ethereum blockchains allow for pseudonymity. 

Transactions can be masked with private blockchains such as DragonChain and privacy focussed coins such as Monero and Verge. 

Use case 1 and 3 exist. 2 is in progress. 

Use case 1: Eth Lend, Salt

Use case 3: Will be solved by payment focussed cryptocurrencies giving close to zero transaction fees, and conversion to fiat will also be close to 0. 

Millennials are right to think this. If BTC drops 90% it will still have beaten most bonds and funds over the last year.

Crypto's largest value proposition is judgement and censorship resistant money. 

There was never a promise of cryptocurrency being an investment. The promise was for the blockchain to decentralize money. It has succeeded at this in creating a store of value, however high transation fees are reducing it's capacity to function as a means of exchange.
