The victim account that the scammer created for the victim on the platform would be getting credited but it is not money but just a number to deceive the victim. If the person pay the money that the scammer told him to pay, that is just how he or she has been scammed.
The number of scams is increasing everyday and it is difficult for it to be prevented. Awareness and exposure of their tricks is what is needed. As for me, any thing that requires me to pay for it first before getting my money out of it, is a red flag and I know that it is a scam. Whether it is crypto, e-commerce, or in any other business they are the same. Scammers always have a modus operandi and they are easy to spot unless their victims are blinded by greed.
You are right, it's very necessary for people to know about something that seems confusing for people to understand because scammers are upgrading everyday which is making most people to mistake them to be the real one.
That is why we should have the knowledge or idea of what we are doing before going into it , even online work should be investigated thoroughly before involving ourselves to be part of it.
