If you can, then just short all the shitcoins. sounds like easy money.
What does shorting means?
it means speculating that will they decrease in value.
So you wait for a crypto to lose value, you massively buy them all because you have a lot of money, this increases the price and then you you sell all of them massively, is that it?
No, you SELL them without owning them (if any exchange allows that.) You can do this in forex.
So basically what you mean by that, is you sell them at a set price of say $0.10 hoping that you can buy them before a preset time at $0.07 ? Is this what shorting is?
No that sounds like more of what's called an "option" when you're talking about preset times.
On the stock market , shorting a stock means you are betting the stock will fall in price. It's not really that important to understand the inner workings of it, but basically you are borrowing the stock from the broker with the money you put up as collateral, selling it, waiting for the price to fall, and then closing the trade as you buy it back from the market. You pocket the difference (or eat the loss if the stock rose).
In the forex world, currencies are traded in pairs like EUR/USD and you can "bet" in either direction. Going up is known as a long trade and going down is called going short.
