What are some of the trading sites you guys use? I'm not looking to short or predict the change in bitcoin. More so selling my person coins when its high and then re-buying then it's low. My main wallet is on coinbase but when I got to sell it's giving me the price I bought in at. Is that how it works? Does that mean going forward I have to buy lower than that? Or is there a site I can sell on the current market price? If I'm asking in the wrong section feel free to direct to me where I should be.
