With laptop, you can mine only CPU coins like Monero. There are multiple other coins as well,  it they are not worth it. Monero is a CPU minable coin so it is good to start with. However, I won't advise you to really use laptop for mining because they are not built to handle that extreme heat generated from mining activity. You will just burn your laptop at the end of the day.

If you have a desktop system, you can probably think it as an option. But don't expect to make a lot of money out of it.
