I think it's better that you do mining on altcoin because when you do bitcoin mining I don't think it will give good results because the level of difficulty of mining is already very high and the results are also very little while the repair costs for your mining equipment are also very expensive, so it's more good altcoin because the price can be expensive at the end of this year and the level of difficulty of mining is not too high.
Results, of course, for sure most of us can only afford to do alt mining but unless you're prepared to make a proper industry of it, get the right education and right equipment, don't ever try mining on your computer or laptop.
I even made the mistake of POS before and made a lot thinking I was smart but those coins just got worse and worse in value. I lost a lot in electricity and time.
