Why does Ether (Ethereum) have value?

Ether, the native currency of the Ethereum network, derives its value from a myriad of different factors. It is used within the Ethereum network to perform a range of functions, including:

• used to pay Ethereum transaction fees (in the form of ‘gas’)
• used as collateral for a wide range of open finance applications
• can be lent or borrowed
• accepted as payment at certain retailers and service providers
• used to as a medium of exchange to purchase Ethereum-based tokens (via ICOs or exchanges), crypto-collectibles, in-game items, and other non-fungible tokens (NFTs)
• earned as a reward for completing bounties

Furthermore, in Ethereum 2.0 (Serenity), users will be able to become a validator and help secure the network by providing computational resources and locking up 32 Ether per validator.When it comes to cryptocurrencies exchange than hundreds of different networks comes up providing services of exchange of cryptocurrencies. Or transfer of eth to PayPal

. But as discussed above people got confused in finding the right place to make transactions. Due to this, it is expected that Proof of Stake will lock a substantial amount of the circulating supply of Ether. There are also discussions around introducing a ‘fee-burn’ model where a percentage of Ether used to pay transaction fees would be ‘burned’ and thus reduce the circulating supply of Ether.
