Im pretty newbie in cryptocurrency. I heard that we need to keep secure our Private key. Do we get a Private Key each time we open an account on an Exchange ie: Bittrex, Poloniex, Binance, Coinbase, etc? or do we get Private Key on each currency? I have account on Bittrex and Binance and Coinbase, and as I can remember they never show me Private key. do I suppose to get one?
I also need to know; Do we need to save the generated address each time we send or receive coins between exchange? the address keep changing each time we send.
And where do I get a Paper Private key?
These are the advantage when you do make use on exchange wallet which you wont really have the possession of your own private keys which is already a part of the risk when you do tend to store up coins on an exchange wallet and this is why its being advised for how many times already that we should not really store up huge amounts because once those exchanges been hacked or compromised you wont really have the chance on accessing those wallet since you don't have the private keys.
