I never invested in Crypto currency from starting i am working for crypto currency, like signature campaign, social media bounty, translation, etc., from the bounty coins i trade and make more bitcoin or lose it. So their is nothing story about loss. Ya but in some projects what i earned free coins i did not sold them when they were in high price due to project being very good and promising but now in the end they are also 90% down and even this project developer also diverting the concept and it is not good for the coin. So this way i made loss of time and effort.

In any trading if anyone is making profit then obviously other will make loss , it is just same like gambling. The only different is in gambling you lose instantly and in trading you lose instantly or in long.
