It's true that when Thunderbit went down, their website started redirecting, but it redirected to multiple websites, not only Bitpetite. Bitpetite responded to that claim a while back, and said they had nothing to do with Thunderbit. Also, Thunderbit was only around for 8-9 days. Bitpetite has been around about 120 days.
I can totally understand if you don't trust Bitpetite. I've been scammed in the past. But I still think Bitpetite is providing a real service, that's how they get money. Thunderbit had no way of getting money, except through more investors.
