Dear Forum members,

First, I would like to say hi all of you as this is my first time here and obviously my first post ever in this forum.
Pleasure to be with you all, and I am anxious to get to know you and learn from you all.

My question may not be so simple, here it goes:
Lately, so many instagram accounts sending me messages about making money thru crypto currency, and they go on with many mysterious approaches, asking too many questions and trying to propose making a lot of money by investing very limited.
I am talking about investing 100 USD a week and making weekly 5000 USD in the following weeks.

Of course these type of approaches reminds me conmen. I would need accept such ridiculous
offers. If that would be true, everyone would do the same.

Long story short, my question is; who are these people? What type of offers I should be careful of? What kind of offers are legit and can be considered seriously?

Thanks in advance for your honest answers. And my question may sound a bit stupid, but bear with me please, I will grow ;-)

Best regards,
