They are really flooding the ICO's telegram group just to scam people these days, I'm so mad at them when I first encountered a scammer that pretends to be the developer of the specific ICO ask me that in order to get the pre-ICO tokens and bonuses we need to send the payments to the provided wallet addresses, good thing the group facilitators and devs intervened with the conversation banned the scammer then put a pinned message to their telegram, what the first experience with ICO well all things works fine after that, always follow the contribution procedure on their website.
