BTC surges past 9 k and short term threats are growing...
Short term positions are always most vulnerable when values are increasing or decreasing rapidly because that's when there's the most volatility. On the other hand, it is also when the most profit is to be had for people who are successful with their trades and in that sense it is a double aged sword.
Short trading is very risky you really have to watch the price movement of every coin. Personally if you really want to experience the real growth then HODL bitcoin, and make yourself busy to other things, yes you are making money through that but you are wasting your time because you can't buy bitcoin as the same price in the past.
I agree with your statement Short trading is very risky. But most people think of wanting to earn money easily without wasting time. I also occasionally experience it, so I have to wait for the coin to go down when the same price in the past.
