I guess since you are a newbie, I would suggest to stick first with Binance so you dont have to worry about the gas fee. You can even fund Binance using your creditcard. Then later on you can start investing using your metamask or buy a Trezor wallet for added security.
This is the best and secured option, though of course your safety will still depend on the knowledge that you have so if you are a newbie, better to limit your trade transactions first while you are still learning about the market. Trading is not easy, and with that capital you should not expect something big in return in just a short period of time. If you already have background in trading then Binance is really good for you.
