I check reviews on internet and found both positive and negative reviews.
What were your sources? Trustpilot reviews can be faked. Also, the domain is not even a year long and I already see
people claiming it to be a clear scam in other forum. Sad that you fell for this.
there is an option to pass KYC for me IF I pay 650 USD to them
Just, just dont do that. I hope you got a sensible mind and can understand the differences between right and wrong atleast. Which legit exchange asks money for a KYC?
I was scammed I guess?
Unfortunately yes, and you or we can do nothing about this now. The money is gone but if the scammer on tg gave you his bitcointalk userid, you can post here so he can get tagged!
