Tell them to buy a Ledger hardware wallet. It's not that difficult. My grandma probably wouldn't know how to use it, but if they're tech-savvy enough to trade crypto on those exchanges they'll be fine. It comes with a nice app/UI as well. However, if your friends are not tech-savvy be sure to educate them about storing their keys in a safe way. Writing their recovery phrase onto a post-it note and storing it on Google Drive is more dangerous than leaving their money on exchange like Coinbase. Of course the hardware wallet come with instructions, but who reads instructions these days?
