When you buy a brand new car it drops dramatically in value when you drive it out of the dealership. Why did you buy it then?
Because you like it. Not to mention a car can't produce more cars.

I buy a certain snake because I like it, breeding it in the future and selling some of the offspring is just a bonus. If you just want to make $ on an investment there are much better avenues to follow that are more secure and do not involve living breathing creatures.

If all you care about are future values maybe you should ask yourself why are you doing this?
