Questions about payments

I just sold my first model, although I only got 2.5$ after taxes and cuts, but still it's my very first "salary", so I'm wondering what's next, I am using Paypal, so is there a limit for when I can receive the payments, does it have to be for example 10$ or will I get the 2.5$ on the 20.th of the month as well?

I live in east Europe and I think that Paypal has a 10$ and I think there's an (additional?) fee of 5$ for my country, so I'll not be able to withdraw anything in real life from Paypal until I get at least some 20-ish dollars, although perhaps I could spend that 2.5$ dollars on something online, like Steam or something, but I suppose that there's limits for that as well.
