Yes, i had the funds there and someone told me that site is better than localbitcoins and i started trusting and using this site. I was away for holidays but today when i checked this new error, it seems that it is sign of exit scam. How many more exit scams will we see in cypto world

How many more exit scams? A lot more, to say the least. It will never end. So take this as a lesson, and learn to use decentralized exchanges like Bisq[1] instead. With Bisq, 1) you don't need kyc 2) you hold the funds, not the platform
Why people cant just simply put up on their minds to trust only those services which had been used by majority? People do really love to explore and then cry later on when problem arises.
One word: carelessness.
