“Long” refers to a trading position where an investor buys an asset with the expectation that its price will rise. When someone goes long, they believe the value will increase, allowing them to sell later at a profit.In practice, an investor can take a long position by purchasing coins or tokens directly. For example, if a trader buys Bitcoin at $30,000 and later sells it at $40,000, the profit is realized from this price increase.Traders can also enter long positions through derivatives like futures or options. In this case, they agree to buy an asset at a predetermined price in the future. If the market price rises above this level, they can profit from the difference.Going long contrasts with a “short” position, where an investor bets that an asset’s price will drop. Hence, going long involves optimism about the market, focusing on potential growth and profit opportunities.
