My mom actually bought my MacBook Air for me a few years ago, and it was really for education purposes and stuff like that. She's super strict. I never get money of my own because I'm only 14 and I come from a single parent family with 2 kids (me included) so we don't make as much income
. The MacBook Air was kinda a one time thing.
If all this is true then the LAST thing you would want to do is burn up and destroy your precious MacBook Air to get no Bitcoins for your efforts. Or best case waste a ton of electricity and run up your electricity bill for a few cents in Bytecoins.
I like your enthusiasm but Bitcoin mining is not a way to make money for you. You will have to find another way. Perhaps you could use your MacBook Air in some other way (write programs, web sites, etc. - I don't know you will have to be creative) to make money?
