Shorting means selling at the current running price and then buying back at a lower price, here it is actually same as buy low sell high just the order is reversed. Shorting needs to be correctly timed otherwise if the market turns around in the middle of the two trades, you will end up in a loss and a bad position.
That shorting of "assume I have it right now without me having it, and I will pay for it later" is the root of all the problems in the crypto world. I mean that makes it profitable to drop the price of bitcoin and people think that it is somehow okay.
I find it the root of all our problems, there are so many rich people see the price going up too much and start to sell it and short it at the same time and make a ton of profit and that is not an easy thing to overcome when you are going against organized whales, hence we keep on being worse than we should be, all because they believe that they could make a huge profit by shorting, if there was no shorting available, we wouldn't drop like this, we would drop, but not like this.
If, in fact, when the BTC falls in price there are many people who win, apart from the whales who do it when they enter the market with Short, which I don't know if you remember in 2018 when everyone expected a good bullish movement, what he did was drop in price quite a bit, and it was when it was determined that BTC investors began to enter the market but in an intelligent way, which is through the Shorts, since when a millionaire or whale enters to buy he always does so very cheaply , the rich never buy expensive, they sell expensive, but they buy cheap, at that moment those who entered in short and apaancados won a lot.
