Dear All
Based on the replies, I read:
- Using a single key pair (old) even for multiple transactions isn't an issue, with the exception of privacy concerns.
- Ensure that the Electrum clients are up to date
- Ensure that the fee is "appropriate"
- I mixed up some concepts: No need to download the whole chain (just recalled that the client shows the current fund level on the key which is from where I got this)
I would say this clarifies my concerns.
My
primary concern was that there is no way I can "lose the coins" this way (naturally excluding compromised machines and incorrect target addresses).
Like e.g. it not being able to return the remaining funds (these concerns were answered
or something similar.
I'm a bit paranoid because back in the days I was unaware that there could be multiple key pairs in a wallet, had a backup of only one of the keys in the wallet and was wondering why the balance was off when I imported it to another instance...
Fortunately I did learn the reason and found the other key, but this kinda left me scarred in regards to making mistakes in the future.
Regarding privacy, "this isn't an issue" as the current and all future transactions will go to a single trusted destination. I know it's bad practice, but as long as it doesn't result in missing coins, it's acceptable.
I would like to express a very big *THANK YOU* for the helpful replies I've gotten!! This was highly appreciated! In case there are any points I've missed, I'm still more than grateful for having these pointed out!
Best regards
Richard
