By your post I could tell that maybe you have lost some value by trading on leverage. I can feel your frustration as it also happened to me in my early years of learning how to trade. I can't say that I haven't been making mistakes every now and then but I could say for certain that I'm not making huge mistakes.
What you say is true and newbies should avoid trading on leverage unless they know what their doing. I also am in the position of discouraging them from it. Although most of them will surely not listen and would prefer to learn the hard way. Which is fine. I makes the markets more profitable. Think of it as something like their tuition.
I did lose, yes, in a couple of days when it just passed the 1000 mark days ago I went from 3 BTC to 10 just hours before it crashed to 900 and lost all. I did lose you are right, but I'm not frustrated or mad, you are wrong about it I cant be mad for such a tiny amount I lose, I posted this because the current tanking is because of that again..
When I opened that long, it had only two conditions: to reach 30 BTCs (1000%) or to burn it all, it burned before reaching 30 as expected. If it had reached 30 then I had embraced and supported leverage.
But that needed crash ended confirming my study, that crypto leverage infact hurts the market and the médium and long term traders, because the mcap is still tiny compared to stocks or forex. High Leveraging delays the true profit from trading 1:1 leverage.
It is really true, you could make 1000% easier money in any forex pair or instrument from simplefx.com for example
