This is a good start where you have bought bitcoin for the first time, I think every time you have the funds in possession then this can earn bitcoin consistently to keep investing in bitcoin and I also continue to buy bitcoin gradually or what is called DCA.
At the beginning of 2023 the bitcoin price is still low this is still your opportunity to buy bitcoin at the base price before bitcoin will recover and reach ATH again, I hope that starting this year will be a whole year where you will continue to earn bitcoin from regular purchases.
So congrats on a great start with your first purchase.
This person also made his first bitcoin purchase in October:
My First Bitcoin Purchase.I do hope that you plan to move bitcoin to your own non-custodial wallet, so you have complete control over your money. My suggestion is
Electrum for start and then eventually a hardware wallet.
The current withdrawal fee to bitcoin wallet from binance exchange is 0.0002 btc, so if the OP wants to withdraw it to non-custodial wallet then of course he will only receive around 0.00011254 bitcoin after deducting the withdrawal fee. I don't think the OP should be doing it now as his current bitcoin value is no more than $6, but if the OP has $60, $100, or higher then I would also suggest he do so.
Since it's a small initial investment there's no way the OP would do it right away, maybe he should at least hold on to the exchange until the fund reaches $30-$50 after which he can withdraw it to a non-custodial wallet that has his own control.
To the OP, don't put too much faith in keeping assets on the exchange, it will be risky, even if later for every $50 purchase it's better to withdraw it directly to a non-custodial wallet.
