Wow, it was truly amazing, $150 is big enough as a giveaway. And it was interesting...
I click the link posted by OP and it looks legit but I never have a try to claim it. I just to ask the OP if the giveaway will receive instantly?
Actually, this is a good marketing strategy for the team, this event will certainly be giving some hype on their project and it will be going known to others. If this is real (as nobody could justify it now), this was a great opportunity for them but have to be careful guys, fake sites can rip you out.
