I am big time follower of ethereum from initial days i was holding ethereum even the price less than 100$ and also i was holding ethereum at the price of 1500$ . But based on recent development i am highly speculative ethereum price after 2.0 release . Once POS introduced the problem of scalability will be solved Maximum supply will be fixed . So i am slowly investing on ethereum from my savings part by part reasons are below
1) Inflation in global curreny or fiat curreny ( ehtereum and bitcoin is best alternative invetment solution )
2) Ethereum is the best Smart contract creation platform holding major DAPP's in market
3) Real world use case
Ethereum is really one of the cryptocurrency with lots of utility and Usecases across the entire crypto market, just like how you outlined in your write-up, the completion and release of ethereum 2.0 will greatly redefine the entire cryptocurrency sector with it's advance features to enable faster transactions, easily accessible smart contracts plugins and scalability. Investing in ethereum will definitely yield profit on the long run
