It is very difficult not to fall into the hands of scammers because scammers make promises that not exist in the real world. There was a year where there were scam exchanges that promised the following:

The person gave $100 in Perfect Money and received $150 in bitcoin

The person would give $100 in perfect Money and receive $150 in payeer

People fell into this type of scam because they wanted to have more money and did not ask themselves where the exchange owner would get money to do these kinds of things.
