I'm not sure what "sweet privkey" is. I'm kinda new to all of this. I was just hoping I could transfer my BTC without losing 200 dollars and maybe lose 10-20 at most.
He made a typographical error, he meant "Sweep private key". It's like sending all of the bitcoins from your software wallet to an address that is from your hardware wallet (involves an actual transaction).
From the looks of that if I do 1mBTC/kb it'll be confirmed within a day, right?
According to that website, yes but based on my experience (from recent unconfirmed TX's, it takes longer for such low fee transactions to receive confirmations [you have to take note that, that website shows estimates on current states and can't predict future states]). I suggest to not use anything lower than 3 mBTC/kb, in case you want the transaction to get any confirmations within the next 24 hrs (from what I've observed lately).
I tried making the transaction and something weird happened. I did a low fee transaction of 1mBTC/kb instead of the default of 3mBTC/kb last night. The transaction size is 2kb.
I started the transaction late last night, at around 10pm. I saw my transaction sending from my Electrum wallet, and receiving in my Keep Key wallet. I went to sleep and woke up to no transactions on either side.
Where did my transaction go? Why did it just disappear?
