Well for a fraudulent activity to be successful, they must make their presentation looks legit. With that they thought of it thoroughly and how to mimic legit company. They think in advance and often prepare answers to possible hard question from these suspecting possible client.
I don't even think they need to do that? They just need to promise a large return and for some reason people stop getting oxygen to their brain. You can see some things are scams yet people invest. They deserve what they get and I feel nothing for their loss. People who invest in scams are destroying crypto. That money could be put to far better use bit people are not interested since legit projects don't promise high returns and people want to hear lies. They want to hear thy will get high returns.
