well i had some issues with bad players on btcjam. the admins dont seem to do much about them as those scammers are still showing up and asking for loans. hell i cant even get the btc out of my account. i have tried several times but the confirmation email never comes and there is no reply to support emails. IMHO just stay away. of course its your fiat.
The support is in fact bad, but the email to confirm the withdraw address it's always sent, if it's not, then yes you'll have a hard time as the support is almost non existant.
i guess they plan to keep my .08273 BTC.
