Ledger Security used with Metamask. A novice I.T perspective.

Please note that the following is not financial advice to anyone, nor would I seek financial advice from a Reddit thread. I'm just fascinated in the technology and want to know the most concrete way (Right now and hopefully in the future) to store it for the long term.

Not a cryptographer so the following is probably a little wrong from a tech standpoint. Please do correct me as I want to learn as much as possible.

Hi all!

Just wondering about possible security issues regarding the use of a ledger hardware wallet combined with a Metamask wallet. I dollar cost average my crypto purchases each month from my exchange into the ledger to save a bit on network fees, however I’m wondering about incorporating future purchases using Metamask and a Ledger (for signing the transactions). I have a basic understanding of layer 2 and how rollups work but would like to know if there’s any security red flags for storing ETH on a layer 2 wallet to save on gas by using Metamask in combination with a ledger so that I’d have to physically unlock the device to sign transactions. I’m a long term holder and see Ethereum just as any other technology asset.

I have roughly 6 figures of capital that I'm ready to add into a long term position in ETH the technology so I guess my main question is, am I better off just purchasing now, then storing it on the ledger (Paying the cheaper network fees today) and for future purchases using DCA, using another L2 wallet as the L1 Gas fees become higher. In the future will the gas fees outweigh the capital I'm trying to withdraw? (Or transfer to become staked)

My ideal outcome would be that I could just buy ETH each month and have it securely stored offline in the hardware wallet for the long term. And then, someday into the future, have the ability to easily, securely, and as economically viable as possible withdraw/access the tokens.

However, I’ve come to understand that the gas fees for Ethereum layer 1 will gradually get more and more expensive as demand increases/scales so I’ve been looking into layer 2 wallets and storage solutions but I’m very cautious/ weary. I understand that computation is done off chain then posted to L1 for the green check. If for example, layer 2 services like Hedera go offline for maintenance/hack does that effect withdrawals/transfers from the wallet? Also wondering if it’s possible to transfer funds from one L2 wallet to another at this stage? (transfer seed phrase into another wallet to gain access to funds)

I’m using 2 ledgers (A nano X and S) and a Cyrptosteel stored securely in a protected environment. None of the tech has been “Setup” as of yet as I am still working out the details. If I was going to run Metamask or ledger live I’d use another computer solely for crypto and/or a “Live” OS running from an external drive combined with a VPN.

The Ledger and Cryptosteel were purchased using fake information and paid for via crypto

Any help is greatly appreciated. I’m still very early on my thesis for Ethereum as a technology but would like to (Just with any other asset) hold onto it in the most secure way possible for the long term and have the ability to deposit/withdraw in the future without the Gas fees eating up too much of my capital.
