What’s the best way to DCA Bitcoin weekly?

Hey! I'm new to crypto and making an attempt to arrange a easy system to DCA by shopping for a hard and fast small amount of BTC every week.

I heard about using the Convert function on Binance because it’s tremendous straightforward—I simply select BTC, hit convert, and it’s achieved. But I’ve additionally come throughout warnings that Convert isn’t probably the most cost-efficient choice on account of hidden prices.

Would love to hear what different novices or veterans advocate! Thanks for any ideas or advice—I’m wanting to study and maintain costs low.
