You want financial independence from your family go get a job. Mining with the gear you can afford is essentially just siphoning money from your parents because they pay the power bill. Save time/money and just loot their wallet/purse outright if that's your intention. Next to no chance to get a legitimate return on your investment with that gear or anything your likely able to afford. Mining is gambling, not an investment and should only be done by people who can afford to loose.  BTC or any cryptocurrency is highly volitile and could drop or spike at any minute. if you really are hardset on getting into crypto your better off just buying the currency outright. Or better yet, get a job and start saving for school/rent.
