Once again, for the OP,
Whatever your decision, approach to do in order to get bitcoins, the first priority for you is:
- Securing your devices (desktop computers, laptops, mobile devices) which you use to connect to your wallets, exchanges' account, etc.
You can luckily and / or smartly to get 100, 1000, or even 10.000 bitcoins, but if your devices are not secured enough, you will lose them all someday.
It's key in crypto, be safe first!
For security, I have a topic on this issue, but you should secure your devices with professional softwares, not free online ones.

Next priority, is to backup your bitcoin wallet for later use, in cases your devices broken, or any case worse.
The step should be done simultaneously with backups of your exchanges' accounts, 2FA, and your emails as well.
For this step, you can find them in the topic I gave in my previous thread.
