Ethereum 2.0 staking will showcase its deflationary property where part of ETH will be burned and as a result it will be more valuable as time goes by. With no more limited ETH, the deflationary model make sense to keep stakers more interested in securing the network while millions of transactions take place from DeFis and smart contracts executions.
This is interesting because AFAIK there will be no stopping on supply of Ethereum coins they dont have any control over inflation. Since more tokens are adopting this model chances are that it will be a big success.
