Bottas has been signed up by Mercedes for one more season as the world champion’s team-mate.
Hamilton is also out of contract at the end of the 2018 campaign but he is in talks to extend his deal.
Bottas said: “For me it's good for Lewis to continue.
“I clicked well with him, and he's a quick driver and a challenge.”
Bottas finished third in his first season with Mercedes but speculation is ramping up about Daniel Ricciardo or Max Verstappen taking his seat for 2019.
But he hopes to win a new deal, and said: “The best contract argument is to win as many races as possible.”
Bottas is already back in training ahead of the new season, which begins in Australia on March 25.
