I started mining with rtx 3060 lhr

Recently i bought a new evga rtx 3060 12 gb gpu and I finally started mining with just one gpu. My dream is to build a mining rig but it's too risky and expensive now so i decided to start slowly. I'm getting at least 1 usd per day and for an lhr card 31 mh is a decent result. I could go with gtx 1660 super at cheaper price but for the long term i think it's the best choice and soon or later Etherium merging will happen which will have huge impact on gpus which are only profitable with etherium mining. I bought my rtx 3060 for 400 usd +50 usd tax which is the cheapest price in my country. The highest temperature my gpu can get is 65 celsius which is the ideal temperature for mining so I'm not worried about my gpu's longevity and I'm planning to change thermals after 3-4 months to keep it cool. If in the future gpu prices fall then I'm planning to build mini rtx 3070ti farm for ravencoin mining. Do you think gpu mining will be profitable in the future or?
