😉 A little help please

So, I am 17 y.o and wanted to start investing. I only have 1000 Dollars in my account.If I buy stocks of 10 units for example equivalent to 10$. Does that means each month I need to give 10$ to make sure I still owned that 10 units or is the stock mine until I sell it?

I am really confused since I just started thinking of investing. So any book or articles recommendation would definitely be helpful.

If this thread is offensive I am asking for forgiveness in advance.


Cheers

Hey man it is yours until you sell it!
