Why some members sell domains so cheap?

If he is happy with $35 a day, good for him, but let's be honest, does your friends buy every day 10 domains for a Dollar each, and sell every day 10 domains, I don't think so. but if they do, maybe they should try to increase the price slowly and one day they will end up with $100 profit per day....

 

I think its either:

1) $1 > $0
2) No use for it
3) Being nice

 

thats what i tell them.and it is not possible to exactly buy and sell 10 each day thats average.They are kind of stupid to the fact that they can earn more.they dont try they sa6y they are happy with 30 to 35$/day.

Thats their wish what can i say.

 

I found People mostly sell blacklisted domains on Google cheap along with the domains they might have purchased for some projects but later on feel that they are of no use

 

No problems with that, but keep the market going up.
Let's say that you bought land 10-15 or 20 years ago, never planed to develop it but during this all time you paid the taxes for the government and the city, would you sell this land for less then you invested in?
