There was a time when a market crash would have led to loss of sleep for the "common Joe," who knew only how to be long in the markets; the short position was badly understood and in some cases difficult to realize in practice. Today, it is no longer a problem to be short on almost any class of asset. Being long or short is in fact a matter of indifference to traders today. They have only one problem: making money by being on the right side of the market. Other reasons why more and more people are supplementing their income through fast trading are the long opening hours of many markets (indeed, the Forex is practically always open) and the ease of trading assets using the leverage effect, whereby the trader owns only part of the total sum and the remainder is financed by the broker.
