I was introduced to this app by friend and I was new to trading. Didn't know much about it. I already stop using the app now and used binance instead but I just want to confirm it was scam and not other reasons why this might happen.

The app I used was ingotsex.vip . The commission are 0.00300000 for all cryptocurrency. I had about 18k usd before the trade and after the trade was done I was left with 6k usd . Thankfully I already made profit before this occurred. I just wonder if there is anything reason for this or its just a scam. I was told it had something to do with volume but I wasn't sure.

Hi guys. I am new trader here. I had previously sold LTC/USDT at $70 at market price but when the transaction went through it show $47 a coin. I double check and triple check the price stay around $70+ the whole day never drop until $47 which is ridiculous. I wanna ask is there a actual reason why this might happen or it just a scam trading app?
