It depends on some of factors.

1. Are you actually day trading? or making a short term trade?
2. Why did you buy that altcoin in the first place?
3. If you bought a certain coin at a higher price and the price lowers then you sell, well, that's automatically a loss. Sure, you can buy when it dips, but what if it dips lower? The point is, we can't guarantee where the prices will go.

Ultimately, if you're new to trading, prepare to initially have LOTS of losses. If you're not willing to do a lot of reading and research and if you're not willing to risk your money at the start of your trading journey as it's almost guarantee for you to lose money in the beginning, then maybe think twice with your plans.

Not to discourage you though, just to keep things realistic, and so you wouldn't be surprised if you aren't doing well at the start.
