Grandbux is simply the best PTC in the world. Their support is extremely attentive, they have solved all the doubts that I have had. They have microjobs insured, because if something happens grandbux responds quickly. Your ads pay very well. And the referrals are always excellent.
You can not order more than one PTC. The best in the world. I have been for 3 months and I already bought a golden membership and I have 62 dollars.
Simply the best investment of my time.
