$SOL
I have no idea from where he found this exchange i never even heard of it but he got interested in that because $SOL was trading there at $139 while the original price was $129. He thoughts its a good opportunity to make some money. He decided to test it with $1000. He bought sol on Binance at $129 and deposited into that exchange to sell it for $139.
Luckily he was able to take the withdrawal. Then greed kicks him he bought Sol again for $2000 and deposited it back to that exchange. Now his $2000 is stuck there and that exchange is asking him for another $1000 for verification purpose so they will proceed the withdraw. Its 100% a scam for sure.
I tried to find information of that exchange on X and google, i found nothing. Not sure how he found it but his $2000 are now gone.
