Ok, so here are some resources for you (and others), to help you get started with Ethereum.
For a general understanding of Bitcoin and Blockchain tech, I would suggest to start with the book The Bitcoin standard, by Saifedean Ammous. I did the audiobook version myself (I believe with audible you get your first book free when you sign up for the 30 day trial- worth it), which was a great, informative listen. Discusses the history of money and the gold standard and posits some very interesting theories.
I could give a writeup on what eth is and what it does, but the hour I'd probably spend on that can be shaved down to about 30 seconds of copying and pasting to give you this video (26 minute watch/listen):
There are a lot of different youtube producers out there, and a lot of them are straight trash. Generally, Guy (Coin Bureau), aside from cringe video thumbnails, is a good watch/listen. He focuses more on what projects do and how they are developing, as well as providing a weekly news update on crypto, which is handy if you want to save time and effort digging through stories yourself. Also, all of his videos are indexed in the timeline. That comes in really handy for when you want to skip a part of a video. There is a producer out there for everyone, though, so if you don't like his content you can probably find something more your speed.
Most blockchains will have a whitepaper. It's basically a mission statement explaining what their blockchain is and what they want to accomplish with it. Here is Ethereum's. It is a long read, but probably the best, most direct dive you could take into Ethereum:

I'll touch on Eth ETF's, too. I'll use the CI Galaxy Etherum ETF (ethx.b), as the example (speaking of, I ended up sellling my options on that for 200+% profit. Not peak, but damn nice).
CI Global Asset Management, a leading provider of Exchange Traded Funds (ETFs) in Canada, offers a comprehensive suite of ETF solutions. Rooted in strong fundamentals, the diverse and specialized lineup of CI First Asset ETFs strive to deliver better risk-adjusted returns than the broad market...

Also, here is a link to a much better written breakdown on ETH ETF's:
Cryptocurrency just got a little bit easier to invest in.

So, this could be the case for all ETF's (I'm not 100% sure), but with this Eth ETF, my understanding is that when you buy the ETF, the fund then goes out and buys the corresponding amount of eth. In the CI ETF, 1 share is equal to 0.003693 ETH. So if we use the old Rate=Portion/Base equation, we get 271 shares (270.78.....), equal to 1 ETH. You do not hold the keys to this Eth, though. The fund does. In the CI fund, they use Galaxy Digital as custodians for the crypto in the fund. This means that you cannot transfer the coins, or use them to generate interest through staking. Speaking of staking....
Eth is currently a PoW (proof of work), coin. This means that blocks are mined and miners are paid a reward (in Eth), for mining the blocks. You may see a lot of EIP-1559 when you search for information regarding Eth. So, the transaction fees for transacting on Ethereum used to be paid to the miners. Now, a portion of the fees will be burned (ie that Eth will no longer exist). This scales based on the amount of transactions per block. So, if Ethereum see's enough transactions, more Eth will be burned per block than what is produced (as a mining reward), causing Eth to become deflationary. The first video I posted goes over this briefly as well.
Eth will be switching from PoW to PoS (proof of stake), most likely some time in 2022, but possibly as early as q4 2021. This is a big change, as it will kill all Eth mining (Eth is heavily GPU mined, which is what has caused most of the GPU shortages around the world), which could have a big effect on the GPU market, if another cryptocurrency that is PoW and profitable cannot be found (looking at you,
ERGO). Here is another Coin Bureau video on Eth 2.0 (6 minute watch):
Hope that helps.
