can you coin control ltci in ledger live? What about those other scenarios i mentioned?
yes, there is coin control in Ledger.
I have never tested, but it supposedly also works in litecoin:
https://support.ledger.com/hc/en-us/articles/360015996580-Using-Coin-control?docs=trueTo use the coin control tool:
In Ledger Live, navigate to the Send tab.
Select your
Bitcoin (BTC) account (or another account that supports Coin Control) and type in the recipient address. Then click Continue.
Enter the Amount you want to send.
Select Fees > Advanced and type in your desired Fee amount.
This website can help you choose the most optimal fee for your transaction.
Have a nano ledger s and i know i can install litecoin app into it to send/receive. Reason why i don't want to do this is because i stored several apps already on my nano ledger s already so i don't want to use any more space on it even though i still have space left for litecoin.
You can unnistall an app and install ltc app in literally 30 seconds.
This won't break anything, and your device was made to support such add/remove apps.
Those apps have about 30kb size.
It is safer to do that than to install another wallet.
