Attiny85 and 433Mhz RF
The code you presented does not fit for working with the RF 433Mhz. I'm not sure what you think this code should do, but this is not the way to go with a 433Mhz transmitter.

I would suggest using a dedicated library for transmitting information using the 433. There are many libraries out there for doing that; two popular libraries would be the ManchesterRF and the VirtualWire, both includes code samples.

For example, sending data with ManchesterRF: 

#include "ManchesterRF.h" //https://github.com/cano64/ManchesterRF

#define TX_PIN 3 //any pin can transmit
#define LED_PIN 13

ManchesterRF rf(MAN_4800); //link speed, try also MAN_300, MAN_600, MAN_1200, MAN_2400, MAN_4800, MAN_9600, MAN_19200, MAN_38400

uint8_t data = 0;

void setup() {
  pinMode(LED_PIN, OUTPUT);  
  digitalWrite(LED_PIN, HIGH);
  rf.TXInit(TX_PIN);
}

void loop() {

  rf.transmitByte(++data, data*data);
  digitalWrite(LED_PIN, digitalRead(LED_PIN)); //blink the LED on receive
  delay(100);
}


In addition, there are many other blogs around going step-by-step how to use 433Mhz Tx/Rx with ATtiny85, google is your friend :)
