Trading with btc - eth, I buy too high ( 0,082 ) and today I sell all on 0,077. Before that trade btc - ripple ( xrp ), make mistake buy 0,0002150 so today I sell with price 0,0001200. I decide to sell all because my patience is finish. I have loss almost 40% from my money, my question is simple ................. stop or continue?
Just don't sell if you see that coin that you bought started to crash down. It's same as to buy bitcoins for 4500$ tell sell them for 4000$ and buy again for 4500$, it's just not worth it. If you aren't patient enough to keep your coins without fear, it is better to stop trading. You still have that 40%, just trade them into bitcoins and withdraw them.
Thing you can do is to keep few $ in exchange and train to trade with them, as probably you didn't have enough time spend trading, so with these few $ you will learn how to trade so you could try again later with more money.
