Staking ETH help

Just bought some ETH and plan on holding it long term. Figured it'd be a good idea to stake it but I'm not sure if its worth. My max is 0.555 ETH and transaction cost is $71. I understand that any money over time is better than nothing but I guess I don't really understand what exactly happens when ETH 2.0 is released. Like does my ETH still get staked even if it comes out? And if thats the case since it *might* come out in near future, will it still be enough to counter the transaction cost? I don't really understand this stuff exactly so any explanation espec eli5 would be nice 🙂 thanks. Also, I do understand that anything can happen and I'm okay with the risks of losing my initial investment.

Edit* I'd be staking it through the ledger app using Lido. Unless there are better option but I feel comfortable staking through my cold wallet.
