How to use Binance Wallet with my DCA strategy?

For starters, I am beginner. So I might respect when you guys actually assist me out.

I just began trading BTC in binance and have been buying small amounts of BTC previous couple of weeks have round $500.

I've traded shares earlier than on Buying and selling 212 where you purchase stocks, maintain on, and promote it perhaps after 5-10 years or whatever.

But Binance Wallet sounds new to me because I don’t perceive what to do after i buy BTC each week. Do I instantly move it to my wallet or let it keep in BTC change (as the value of BTC goes up or down). I see the “Obtain” button on my pockets and then the option of “Transfer from Binance Trade”

I assumed after you buy BTC you own it anyhow. And if I don’t own it, and once I transfer to my wallet, does my $500 cease rising if for example BTC goes up by 10%?

What do yoy guys do since after buying btc every week/day/month? Please explain! Thanks!!
