From here, some members encourage me to join elebux and piggybank gpt under them. They say that both sites are legit, and I can earn a bunch of bonus, and I won't regret from doing it. I just curious both websites, and I want to know if anyone vouch both websites are legit, and I would join them without doubt. I just hope that I won't waste my time, that is all. Thanks everyone!
