if 5000 people sent me $3 each, and paid the necessary $0.14 fee for example, how come I need to pay x20 fee more than them? what the fuck for? this is completely stupid.
For each OUTPUT (in your example 5000), you require a signature. Each signature carries a certain amount of bytes which increase the size of your corresponding transaction. The bigger your transaction the bigger the fee. This is basic Bitcoin knowledge. I highly recommend that you calm down and start reading through the basics again. Ranting won't help you nor change anything.
