I speak Portuguese, what you get out of it all? I say, you show us the software or the method and you earn?
Why must it be $ 100 of deposit and not any amount of deposit

Can be any amout but as the robot works with 50% of your account balance and it works better with more than 100 dollars, so it is better to transfer at least 200 dollars in bitcoin, I deposited 430 dollars 11 days ago, now I have 518 dollars.
If you get the robot from me I earn 15% of your profits and if you send to someone else you earn 15% of his profit, the developer earn the other 15%.
