Enjoy your $3 profit Csmiami used Freebitcoin's slow withdraw to return ArmandoComellas's 0.003
BTC (minus tx fees). Freebitcoin's withdraw fees are dynamic, but fees have not hit around 800 sat/byte which would cause a 0.3 mBTC withdraw fee. A reasonable
maximum would be around 0.05 mBTC (5000 satoshi), and thus Csmiami pocketed 0.25 mBTC+ (roughly $3 USD with current exchange rates). The 0.05 mBTC figure is a rough estimate based upon a
120 sat/byte fee for next block, though the 'Slow' withdraw option is a batch transaction and the fee charged is likely based off of a future estimate for when the transaction was sent. It would make little sense for any algorithm to assume that 120 sat/byte would last, and a more reasonable guess would be around 0.037 mBTC fee based off of the current charge of 0.034 mBTC.
FFS, are we really going that way? I was having some drinks with some friends at a bar, when withdrawing I saw fee was roughly 3xxx, amount he sent was 0.003, so 30-3=0.0027. It didn't sound off when doing it, and since it was not something "urgent" or "pressing" I didn't really double check with a calculator. My bad there I guess....
Csmiami is likely doing this with malicious intent - the 'borrower' does not seem to know how Bitcoin fully works as shown in
this post, and thus may not know what a reasonable transaction fee would be. It is a small amount, but I consider these actions untrustworthy.
If my intentions had been malicious, I would not have repeatedly said "0.03 for 0.015" on every message I sent from the begining, I would just say it once, never mention it again until payment was (obviously) not made full and the I'd have started bitching around how he didn't send me the money or something. I honestly didn't expect him to go as far as to send me any BTC, and when that happened I turned to consult two other members that had been active in the discussion, since those funds were doing me no favour. Also, if my intentions would have been malicious, I would have not returned any single satoshi....
My god, a double red neg over 20k satoshi? I thought I had made myself pretty clear a couple of times about not really wanting to be involved with those funds, this started as a joke/experiment but ouch....
