I actually got 2 old computers(that are way worse than laptop) But they dont really start up. So in order to buy them new  things to make them  work again it would be a huge investment for me(i am only 19 without a job currently).
Should i use  My laptop..? my friend told me that its a bad idea because it wont mine enough btc   and its just not worth.
 my laptop has these
8Gb Ram
Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz 2.60 GHz
64 bit...?
I am not an expert at this tbh . Any opinion/reply will be appreciated !! Thanks a lot
