Future trading is so risky! It's scary, I did it a few times, and I almost crashed out and got out by skin of my teeth and I did demo and every time I did demo I crashed to zero and had to reload and try again. I do spot trading and my rate of being wrong isn't as bad as futures.
I know they are the same thing because if it goes down then it goes down for both and if it goes up then it goes up for both, and somehow, whenever I buy spot because I think it will go up, it's likely to go up, and whenever I sell because I think it will go down, it mostly goes down, futures isn't like that because at futures when I open long then there is a big chance it goes down and whenever I short then the price may go up, don't know why I am good at one and bad at the other.
That's right, I did not knew at start how risky Future trading was, as my first trade ever was in future AFAI remeber, therefore the risk was not that much to me, and the first spot trade I made was in Gala token hehe, and I also made lose from that, and I also made lose in future trade too. But after a day I made profit from future trade and at the end I rekt my account and after that I never went that way because I was just fed up.
In future, exchanges mostly manipulates, and what you experienced is just a indication that, in spot we don't have liquidation gun on our heads but in future we are on gunpoint with this liquidationand the pressure is huge and we emotionally disturbs our trades and plan too.
