Do you have funds you want to use or is this just for when you do?

Electrum has an option to withdraw lightning bitcoins back to a wallet address without closing a channel which might be one way you could do this. (I think they just charged transaction fees but I'm not sure if there was anything extra I've missed).

Use https://www.walletofsatoshi.com/
It's a custodial wallet so don't leave your funds on there for long but they do the entire back end for you.
You can send lightning to it and then send the funds to any segwit address you want.

Yes, in theory they could implode as you are moving your funds but they have been around for a while and are active in development being a wallet. Not something I would loose sleep over unless you are talking about a whole lot of money. And they you just chunk it out into smaller amounts.

I don't think a synology NAS is going to have nearly enough RAM or CPU power to run umbel. And then you have to open channels and to other work too.

the way LN works currently

if you have msats stuck in a LN channel with a CEX as a co-channel  partner where you never had a LN node yourself.. (EG your using their app)
they have both keys for both sides. so you would need to ask them to close session to credit your CEX account and then withdraw

if you have a LN node/wallet you can send those msat to your node..
but here is the thing. currently LN is a double layer

when setting up LN for first time people set up a LN wallet seed.. they move BTC network coin to a address of LN wallet seed key for the LN node(a 'master' LN wallet key) in the node. and then move again into the channel LN key.. where the channels withdraw/close session destinations are back to the LN master address of the LN seed wallet

yes you can import that seed into a bitcoin wallet. by finding the LN seed in the LN wallet and copying it over. but some LN nodes methods of backup/access to that seed is not easy

so then some people just make another tx from the LN node to a bitcoin node wallet

Buddy, that's what happens when you move conversation from bitcointalk PM to Telegram and then share suspicious files, while talking nonsense.

First of all, it doesn't make much sense to me that someone who is in crypto mining since 2014 (according to your post history, but I think that account may have changed hands sometimes between 2014-2018) sends unsolicited PMs to other people, asking some basic questions. 2nd, just 6 months ago you were asking others how to protect your crypto wallet, and now suddenly you are an ex Intel computer expert that sold "secure system for storing bitcoin" to Nigerian government for $40k. Also, your story how Ledger and Trezor are not safe as any system administrator can easily hack them is another bs.

Don't worry
We'll figure it out

Yes,i will
