Hello,
I met someone on internet who suggested that I invest in a crypto trading platform that I didn't know about. I did it step by step and made sure that it was possible to transfer the funds back to binance at any time. So I increased the volume and today customer service is asking me to pay 10% of my capital as a fee. What's more, they've told me that I can't pay this fee with the funds available on the platform, but that I have to pay it with funds from another portfolio. If I don't do this, I won't be able to recover my funds on this platform.
I find your narrative to be amusing. What is it about this that you can't figure out on your own? You must already be aware of the solution, so why bring it up here again.?However, if you are aware that you made an investment in the platform from which you claimed to have received a call, they may call you to inform you of the status of your investments and to identify which legitimate digital investments you have made. If they have the time, they may even contact their customers to ask for a 10% payment to gain access to their investments. That is something I have never heard before. Therefore, if you are aware that you invest, it is acceptable for you to continue researching on them and learning more about how they function. However, if you haven't done business with them, why are you bordering yourself?
Do you think this is a scam or can I pay safely?
This is unquestionably a scam. It doesn't seem plausible to me that you could get a call like that from someone claiming to be from a platform where you made an investment. It's up to you now to decide whether you want to pay the money or keep it safe; even if it's real, you need to do some research about it before doing so. That is, if you know you have an investment there, you should know how they operate.
