Firstly, this is a local thread with "only" local language.
I know it is a local thread, but I don't speak Turkish, sorry. I could use Google Translate, but that probably would be worse.
Btcturk is a legitimate company with many users in Turkey as well as some other countries.
Really? A legitimate company without ANY contact information on their site, not even a phone?
With obviously bogus phone numbers in whois records. The company address is probably bogus too. Couldn't find on the Internet any mentions of "Bitcoin Tranding Ltd".
But the beauty of this scheme is that it's very hard to prove they use all the information you have on you. Their operation is probably honest, because they can be traced by the bank account they use. But it's hard to prove any criminal "side-business".
One has to provide the proof when blaming another.
If I had proof I would go to the police, not the forum. As I said above, it's very hard to prove, but they are the only company in Turkey that has my phone number, used for my online bank, they have a copy of my passport and address (because they say they need to verify you - yet don't like to be verified themselves) and at the same time my bank and my bank account number! They can also estimate how much money is in your bank by the size of withdrawals.
Recently my SIM card was cloned, so my phone stopped working. Meanwhile the attackers were calling bank support line to try and get access.
Luckily, they couldn't.
The only proof would be if they did it multiple times. If several people here will say they had their SIM card suddenly blocked, then we know they are thieves.
