Quick question about Binance trading fees

So I´m setting up my dca strategy and wondered, whether it would have an impact whether I buy 100$ worth of one coin or 10$ worth of 10 coins.

​

For example:

100$ worth of Bitcoin with a 0.1% (respectively less with BNB) fee in one transaction = 10 cents fees

10$ worth of a shitcoin with a 0.1% fee in 10 transactions = 10 * 1 cent = 10 cents fees

​

That should be correct, right? Or is there like an invariable base fee for each transaction?

​

Thanks!
