Never leave you coins on an exchange, Binance is an exchange. To have full control over your asset, use noncustodial wallet. Cold wallets are safest wallet type.
Right. I have seen a couple of such kinds of posts about new investors into Bitcoin and most of them never mention how they have secured their Bitcoin investment by moving it from exchange wallets to any none custodian wallets which is also the first thing you should consider while investing in Bitcoin.
Anyways, I believe OP has made a significant step by being able to make this first investment, and hope you will be able to hodl on considering what can happen with the market price which is also very important with investment.
