It seems to be a very huge improvement as its the 3rd stage of Ethereum Cycle
From what i read
- Block time will be reduced and optimized
- POS integration time by time
- More flexibility of Smart Contract?
- Zero knowledge protocol
Is this the main benefits of it?
It is very possible that ETH might break the $400 ATH if the Hard fork are successful i guess
Actually, whether or not these are improvements might depend on who you are. If you are a miner, then you will not like that rewards are almost halved. You will also not like that it will only be some PoW. But if you are a large holder, sure you will enjoy some PoS.
If you are a heavy user and ICO specialist or dev, you will definitely like the new changes. With the update, there should be less loads and less downtimes. Only time will tell.
