The EXACT same thing happened to me last night (almost). By sheer luck, no ATM drop-box was available. After I got home, his BTC price had increased by 4000+ (in a few hours??? wtf?)
Thing is, this was supposed to be a face-to-face on localbitcoins.com. But instead of keeping up to what was advertised (ie. doing the transaction at my place, I was asked to meet him and hand him the cash and wait for acknowledgement. BUT I had to go to his website trybitcoin.in and register and do it there. So the price on localbitcoins was 18000 INR and it increased to nearly 19500 INR. Not much, difference, but it's the principle involved.
When I asked him why he left Unocoin, I did not get a proper and clear answer. This was really fishy, so I cancelled the deal on localbitcoins and reported it. (Guidelines were that users were NOT supposed to be redirected elsewhere to do transactions!) I'm an idiot for not reading that, but thank God I could NOT find a drop box on time! Then I saw this report and thought.....exact same MO!
What the hell man? I thought this guy was some bigshot and trustworthy and all???
Really depressing. And he was the only one willing to do Cash Transfers face-to-face! Now I'm stuck! Thanks a lot vikram nikkam. Your site does NOT even let me CANCEL my damn order! Your site is registered to a GMAIL address. Even google reports the site as borderline in terms of trustworthiness (51%).
I don't know if anyone else has encountered this, but this was my experience yesterday and now I'm friggin paranoid about doing business in BTC n India!
