Interact e-transfers are high risk there reversible your unlikely going to find someone to trade with on here with your reputation. I suggest using localbitcoins.com but your likely going to have to pay over 15% of bitstamp rate because of the risk involved..
They are not. I contacted the bank and asked. The only way their reverseable is if the sender has stolen the account and both parties has the same bank, then the bank can do a so called "internal reverse" its since both parties has same bank. But if its different banks then theres no chance of reversal even if stolen account.. You should investigate good before comming with comments like this.
