Scalping has the smallest profits a trader could get compare to swing trades and day trades, so using the term "practical" is not suited for it, "safest" I think suits it the most. Even with the small profits in scalping, losses on it is only minimal compare to the two other trading ways that I've mentioned, in short, we can call scalping the "safe zone" in Trading, in my opinion.

No matter how small it is, if you add all of your profits, it could still be bigger, not that big but better than having no profits at all.
