You might have come across bad advice or even a platform that wasn't fully transparent, which could have led to the losses. If something feels suspicious, it might be a good idea to check where you're trading and what kind of support you're getting from that platform.
Trading is stressful, especially when you face losses...
But i think futures trading is great if you know how to do it and have a strategy, and I definitely don't think it's a scam.
