It is very hard to trade successfully in today's market conditions. My last successful trade deal was 263 days ago according to etherscan. I remember that I bought a big amount of some coin at Etherdelta just after ICO ending and when after 10 days it was listed in big exchange and I sold it. I bought it at 700 and sold at 3500 usd. And it was my last great deal in cryptomarket 
If we think and are more careful, actually from that difficulty we will understand the process and make a new experience in our plan. It means taking the positive side or wisdom from a difficult situation, usually will get something valuable.
