It is frustrating to be scammed but that's it, we feel sorry but we also learn from our very own experiences. Next time, OP will avoid projects that are doing the same and will be more careful to check things out first before sending any amount.
He'll be more curious and validate the addresses he'll send not just twice but many times.
