Why should i do if an investment company tells me they can guarantee me $10,000 a week profit on a single 1,000 digital coin purchase ?

As a general rule of thumb, if they come to you, they are a fraud. If you go to them, they are more likely legit. Also, any place that makes you promises such as this is almost certainly a scam. Ignore them and walk the other way.

Why?  Because they are crooks looking for people dumb enough to eat horseshit

know they are lying

Run away as fast as you can.

Only scams guarantee profit levels

Run away.  Only scam artists offer those types of returns.

In theory, they could offer you even larger amounts because they know that they aren't going to pay you a cent.

Run.!!!!!!!!!!!!!,,,,,,,

Report them to the FBI.

Turn them in to their regulatory body.
