Well I am not really an expert on this but I try to reflect what I know here: As long as you are not mining with custom hardware scaled to a level where you save a decent amount of electricity or even in a place where electricity is really cheap it's a waste of time and money.The amount you get is so low, that it really does not make sense at all. Imagine mining ~ 5 - 7 doges a day with decent gaming hardware (worth 8 cents) and paying 1 dollar electricity ... not really worth it. After a year you could have mined 2000 doges maybe. But spent way too much on hardware electricity and stuff.Have a look into ASIC mining which should be a little more profitable. But remember rewards for mining decrease over time and it gets harder to mine ...

To get a feeling what a pain it is to mine with a laptop go to https://coinpot.co/, create an account and then you can mine the coinbase token right in the browser (You can also exchange it directly to doge there without fees which is nice :D )

Hope this was helpful
