i just wanna see if it works to, to convice my sister to put her computer to mine and to convince my parent's to buy me a new one, or if someone give me a loan i will gave it back in 3 months , need less than btc ofc i will give all my info, card drive license adress : )
Of course it works, it is a computer and it computes things till it's broke.
Or if you mean works as in makes money? No, it will not make any money. You will simply destroy the thing. Unless your sister is a computer gamer her computer is likely totally worthless for mining as well. Even then (if she is a gamer) you've got a 50/50 shot of her computer STILL being mostly worthless.
You have no idea how to mine and are already asking for a loan specifically to mine? Are you insane?
