Ethereum is the world’s programmable blockchain, has a native cryptocurrency called Ether (ETH) that has many features.
It is purely digital, and can be sent to anyone anywhere in the world instantly.
The supply of ETH isn’t controlled by any government or company - it is decentralized, and it is scarce.

Store of 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 (MakerDAO, Compound),
can be lent or borrowed, accepted as payment by certain retailers and service providers use it as a medium of exchange to purchase Ethereum-based tokens.
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.
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.
In addition to utility value, Ether also has speculative value.
This is value that is derived from speculative activities (such as trading and investing) which currently accounts for most of the value behind all crypto-assets.
As observed in 2017, crypto-assets can attract substantial speculative interest, with some assets increasing in value by 1000x over just a few months.

We see in the graph how the highest value was reached in 2017: $1400, but 2017 was the year of bitcoin, with the race for cryptocurrencies and ICOs,
this bull run will focus on the Defi and the queen ETH, so nothing prevents us from speculating at least an x10 on ETH.
