I am feeling sad as i being in crypto space for long time now until today i always make a mistake in investment. I should stick on bounty instead putting my own money at the risk. Learning and failing still not changed at all the way of my life. More likely to going down the hill as i am very bad at trading. 
be investors instead of traders then, being a trader is really difficult honestly, not everyone are committed but with investing at least you just invest and thats it.you should realize that maybe you are losing until now because you are really eager to make profits meanwhile its not gonna be that easy.
trading requires you to have extensive knowledge of how the market trully gonna works.
there's reason why majority of people are reliant with trading signal and even copying the trades history of reputed traders because its just simply difficult when you have limited knowledge in regard of trading itself.
therefore its not that you are that bad its just that maybe the market is too difficult to make profit.
