Cristante is on-loan from Benfica and is due to sign permanently for €4m.
“I am pleased to hear I'm worth €30m, but in today's market that is the sort of price you see now," Cristante told L'Eco di Bergamo newspaper.
“If something comes up in the summer, Atalanta will talk to my agent about it."
Juventus and Tottenham are the latest to be linked with Cristante.
“Meanwhile, I'd like to reach double figures for goals this season, seeing as I have scored eight already, but I only care about goals if they help my team reach an objective."
