A day trader isn't going to win 100% of the time every single day. So yes, if you're a supertrader who wins big every single day instead of just swing trading, then sure you can build networth quickly leveraging to the max every single day. But clearly nobody can do that. Otherwise these day traders will have exponential returns and they ought to start their own hedge funds. But with a day trade you're up against a lot of BS too like stop hunting and daily volatility that can stop you out early.
A swing trade just looks at trends on a longer term scale, and your levels are larger accordingly and you will not be a victim to daily volatility hitting your stop loss. Its also a lot less stress. Price moves to your level, you enter a trade and walk away. If and when it hits levels you take profit or take a loss. This can happen over 1-2 days. You don't need to be glued to a screen. You can go read the news while it plays out. With a day trade you're glued to the screen on a second by second basis looking at each tick move.
Anyway like it was mentioned, there is no right way to trade. You trade what you know and what you're good at. Whether that is day trading or swing trading. Just saying that day trading is better because you can use higher leverage on a day trade because of intraday margining rules, is just ignorant. Its about reaching the target $$ amount that counts. With such a high day trade leverage, your stops are gonna be miniscule compared to what you can take with a smaller position in a swing trade. Your highly leveraged day trade has way less margin of error in the trade execution. It is highly unlikely you can pick precise tops and bottoms to enter trades. A swing trade allows a better margin of error in this timing.
