Could someone summarize that Portuguese nonsense because all I understand is a date saying:
ThiagoCMC prometeu pagar até dia 27/03/2013, 60.00 Bitcoins.
Considering 27/03/2013 the repayment day, then ThiagoCMC was late 2 days and now you (rudrigorc2) refuse any payment and want to keep 120 BTC worth of hardware? Unacceptable and totally inappropriate. Add a small late fee like 1% / day he was late to the 60 BTC and give him his avalons. Otherwise I consider you a thieve and you according to my opinion deserve a scammer tag.
And regarding this:
[...] but dont consider the machine yours yet, cause its not, you never had the coins to put in it in the first place [...]
He took the loan and bought the Avalons, taking the whole risk of avalon to default / ASICs getting shiped broke / ... whatsoever. If you wanted an avalon you could have asked for a 50/50 ownership split in the beginning but that was too risky for you and you gave him the loan. Now you see a possibility to scam 2 Avalons for half the price. Thats how I and the rest of the community understand this story.
