When an investor wants to trade cryptocurrencies, he uses an exchange to operate short or long. That is, you will go for Long if you think the price of a crypto asset will go up and short if you think the value will go down. A short and a long position are two of the ways to obtain profitability when trading. Basically, the goal is to buy low and sell high, or sell high and buy low again.

Sell/Short is a transaction in which you borrow securities to sell at the current price, with the aim of repurchasing them later at a lower price and earning the difference as a profit.

Buy/Long is when you buy at a low price and then sell at a higher price to take the difference as a profit. 

Remember, Sell/Short is a transaction in which you borrow securities to sell at the current price, with the aim of repurchasing them later at a lower price and earning the difference as a profit.

Remember, Buy/Long is when you buy at a low price and then sell at a higher price to take the difference as a profit.
