So my question is: Once i buy my first bitcoin, what exactly do i do with it?
Do i leave it in my coinbase account? Is it safe there?
Or do i transfer it to my desktop computer?
I'm not familiar with this yet. I plan to always keep a balance of 1 bitcoin in my account for 5 years to 10 years,
the rest of the bitcoin i buy i will spend online.
What is everyone's advice?
For the amount that you're not going to spend it's best to place that in an offline wallet
The rest you could keep in your online wallet. Make sure to make backups of your private keys
