I agree I think fully entrusting everything to a friend is the mistake here but if you really want to do it then the least you can do is at least try to learn. Maybe get your friend as a guide and use his expertise so you can learn and eventually do it all in your own without the help of anyone.
You dont have any friends in the crypto trading sector - something you learn from experience. The people who might think as friends, you may get scammed by the same. So I would not trust anyone with my money unless I know from in real life for a long time.
For trading, it is not difficult to learn. Besides if their trading experience is poor, they can just buy bitcoin from time to time and not think about trading on it.
Never engage with anyone calling themselves some sort of "fund manager" because these scams are also common.
