As i like to say, Estibot measures potential, not dollar value.
Like getting an advice from a magic eight ball.
Chances are that if it is valued at $5300 by estibot, you should take the risk and register the name.
Let's say there is 5% chance that estibot got the value right, 20% chance that in average it has overestimated by factor of 10 and 75% that it is a crap.
The expected net present value of the registered domain then would be 5% x 5300 + 20% x 530 + 75%*0 = 265 + 106 + 0 = 371 (minus registration fee).
