Ok, first post here. Thanks for accepting me. ๐
I have been taking several cryptocurrency trading and investing courses (5 so far) which generally have been great. However, I'm confused about the "public vs. private key" thing.
I mean, I get it, you never show your private key to anybody. Easy enough.
But when do you use it?
If you want to withdraw your money from the exchange, you use your public key. But then, if you wanna send your money back to the exchange, you use the public key from your exchange's wallet?
So using your private key would be limited to getting your money out of the system (cashing out)? Because even if you purchase something, it makes sense (at least from my completely uninformed point of view) to use the seller's public key to make the payment...
Can anybody please help me out? Thank you all in advance. ๐
