You know, it doesn't happen everyday but this one almost never happened on my gambling history

:

Feeling bad for auto cashout on 300x multiplier >
Wow, I have never seen that on Roobet’s crash before.
That multipliers was enough to buy you lambo hurracan with just $0.1 lol

I want to ask about the promo code. I saw on twitter that roobet official account regularly share promo code to followers. However, I entered a promo code from a fake roobet account (@_roobet_).
What could be happen to my account when I enter that code. Is it safe?
