Hello I dont understand I bought for 4000 Eur one hour ago of Ethereum when it was going up, it stayed around the 10-20%, it started to decrease 5 minutes ago so I sold it and now cex.io just gave me 3500eur for it... wtf... 
The %came from me watching livecoinwatch.. Cex.io doesnt have the accurate price ??
I think the main reason why you lose in trading is because your knowledge is not enough. You should improve your knowledge about cryptocurrencies through reading news and articles. You can easily regain your losses if you have a lot of knowledge. The %came from me watching livecoinwatch.. Cex.io doesnt have the accurate price ??
