Bottas recently claimed his first rally victory at an event at Circuit Paul Ricard, driving a Citroen DS3 WRC. He also entered the Arctic Lapland Rally last January, finishing fifth in a Ford Fiesta WRC.
"It's too early to say," Bottas said. "You never know what's ahead in life or what's gonna happen so but at the moment I like it. It's a fun thing for me to do and I like it.
"I also think it's good for me to try it and to have something different for my skills. I haven't thought that far and I still see myself in Formula 1 for quite some time.
"There is still lots to give and lots to achieve for sure. One day, I'll see what I want to do but for the moment I find it a lot of fun and I would say never say never."
Bottas also admitted that he thinks 2020 will be an interesting season thanks to the number of drivers' contracts expiring at the end of the year.
But Bottas said that he would hope to continue at Mercedes into 2021 as he feels that he works really well with the team and that Mercedes encourages him to become a better driver.
"I think it's going to be an interesting season for sure. I can't remember a time where so many people are expiring with contracts. Of course, me, like every other driver will look at all the possible options.
"Now, if I could decide on my future for 2021 it would be a no brainer to continue with this team. I really enjoy it here, we are performing better and better and I am becoming a better driver all of the time."
