People aren’t against mining on a laptop for the power usage, it’s because of overheating.  Laptops aren’t designed for continuous CPU/memory usage and therefore don’t have the cooling needed for 24/7 mining.

But, if you want to try it, I’d suggest downloading the Minergate software, running the benchmarks, and letting it pick the best coin to mine. A lot of people started out with https://minergate.com before getting serious.
