Guys anyone know Bulkoil app

I recently came to know about this app and started using it. I’ve been trading TVF/USDT there, but honestly, I don’t have much knowledge about it.
I’ve made some profits as well, so I was just curious to know whether it’s actually safe to use or if it could be a scam.

I’m not able to find TVF anywhere else; I can only see it on this app. When I asked them why it isn’t available elsewhere, they told me that it’s “unlisted in public markets.”

So I’m a little confused and wanted to get some advice. Should I continue trading there, or would it be better to stop?

I don’t really understand how all of this works. I’ve mostly just been following the group and placing trades whenever they tell me to.

The profits I made I withdrawed and it was successfully transfered into my bank account
