So using those examples above and/or going with the default setting in Electrum, can somebody please tell me what the "approximate fees" would be for BOTH me and my friend at the current rate,
The required fee rate for getting confirmation is now higher than when I made those posts.
In the last block, miners included transactions paying the minimum fee rate of 15 sat/vbyte. Of course, I guess the network will get back normal soon and fees will become lower.
If you want to make a transaction now and you want your transaction to be confirmed fast, I suggest you to set the fee rate to around 20 sat/vbyte. If you are not in a hurry, you can even set the fee rate to 1 sat/vbyte.
Again, chances are the required fee rate is different when you are reading this post.
According to your previous post, you are going to make a transaction from a legacy address to a native segwit address.
If that's the case, your transaction (virtual) size will be around 190 vbytes and you will pay around 190 vbytes * fee rate (in sat/vbyte) as fee.
For example, if you set the fee rate to 2 sat/vbyte, you will pay around 380 sat as transaction fee.
To know how much fee you need to pay for your transaction, you can visit
mempool.space and you can also use electrum's own fee estimations. Both work well.
therefore I'm trying to figure out a "rough estimate" on what the total cost would be for BOTH transfers if I send my friend 0.3 BTC (approximately $30k).
Take note that the fee you pay for a bitcoin transaction doesn't depend on the amount of bitcoin you send.
