Being scammed isn't very pleasing because it will leave you staring in walls overtime. Even professionals are getting scammed especially novice. I've been there but even though it's not a large sum, still I worked hard for it not to go in waste.
I don't think it's mainly about being professional because scams can happen for totally unexpected reasons. Some users got scammed because the exchange where they hold their savings was hacked and can't refund hacked amount to users, so in this case we can't blame them if they are professional or not.
Absolutely true and scam has nothing to do with professionalism,
because it's all out of their control and indeed this is what worries us all,
scams and hacks can happen to anyone so be careful and stay alert
