Also, as I explained before, to send just 6BTC from my wallet at a normal fee range (few hundreds satoshis per byte) I had to pay hundreds of dollars. My wallet wouldn't have charged me more than I needed to pay but obviously most wallets like electrum generate lots of inputs etc so the more you send the more the fee would be.
Weird. I just sent $13k worth of BTC and only paid $0.67 in fees.
Here's the transaction, since I know you have a hard time believing things I say.
Wallets aren't very good at estimating fees. I use
this page to figure out how much fee to pay.
