Hey there, I've got replies from most of exchanges, the cheapest one says 0.04 (or something about) BTC.
The thing is that I (at the moment) afford that amount of money, not because I don't want to do it, but I don't have that amount of BTC, or even cash, because as you may see in my signature I'm 16.

I'm still looking for other exchanges (thanks to creator of this site: https://www.cryptowisser.com/exchanges/), and I'll update you how is it going.
