lol, no video. The public key is only the address that can be looked up on the blockchain explorer, but to transfer the coins from one address to another address, the private key is needed
See this public address 17HzvxMhoke5K3oavLzPGkLy4zd35KjWEb has over 119 bitcoins? I cannot transfer those bitcoins to Coinbase and sell them since I do not have the private key to that address

K, K, no video. I cry uncle on this one. I am not versed in the public/private key thingy. When I see talk about keys, all I think about is Pretty Good Privacy and try to remember how THAT all works. I found it fascinating back then.
