exchange 
??
??I've contacted several exchanges and asked for pricing
and what did they tell you and did you pay somewhere for the listing or not
??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.
