I’d like to join the network, pursue my interest and be able to pay my bills thanks to bitcoin
Bitcoin is not magic money, you will have to invest in it in order to profit, or offer your services in exchange for bitcoin that you can then sell.
My Mac is too old, not eligible for updates so that I could run bitcoin as well as sluggish with music and my finance situation is not going well for various reasons at this particular time.
Why do you even need to "run bitcoin" in order to use it? That just doesn't make any sense at all.
I don't want to sound too harsh, but what you are doing just doesn't make any sense at all, asking total strangers for money, and especially not for such a bad reason.
