A trader has the opportunity to make a decision thanks to technical and fundamental analysis, as well as news that affects the markets, such as those coming from Trump. Unlike a trader, a gambler can only rely on luck, with the exception of sports betting.
This is another example that totally differentiate trading from gambling, the crypto or forex market can be affected my some news release meanwhile gambling results is not usually affected by any news. Once someone stake on a game, there's no way a new can cause the bet to be successful or bad but if one is taking a trade, a news could come up and it can cause the market to quickly change direction.
