Mining an altcoin now is worth it but for bitcoin I don't think so. But we should always remember that we are taking risks, we don't know if that altcoin can survive in the crypto world for a long run and can help you to make profits. It requires outstanding hardware components for you to feel that you're really earning...
I agree with you, it's very hard to get bitcoins on your computer. It is necessary to make large investments in the purchase of equipment and payment for electricity. In the end, you get very little
Its not worth to invest in mining now as it will require capital to buy equipment and if electricity cost is higher in your country then it won't give you the best profits that you are looking for so the best thing to do at a moment is buy bitcoins and save them for future to earn good profits.
