I just took a trip to the bitcoin machine and there was 4 option Bitcoin Dash Ethurum and Litcoin. I picked bitcoin as that was the currency i wanted. However on the recipe I am saying i have BCH instead of BTC what is the difference would this affect anything as i done it before and I have not received anything in my wallet ever since. Have I just lost my money or?
