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 are right, of course this is the wrong choice if we completely entrust the investment to other people without understanding this well and I also agree with you that it would be better for us to study well first so that we can really understand it well before choosing. to entrust the funds we have to someone, it would be very good if in the process of learning about investment there was a friend who accompanied us so that he could direct us to do the right thing with the funds we have, because without anyone guiding us in learning Of course this will be difficult to understand and we also have to be very careful with the funds we will invest, don't let us use all the funds we have and leave nothing for the emergency funds we need, of course this will not be able to achieve our investment targets.
Wrong choice to the fact that there's huge money involve in discussion and he might see the true color of his friend if he entrust his funds to his friend just to trade for him. OP should remember that money could expose the real attitude of people so to avoid getting any issue with his friend much better if he decide to trade for his self. Being so lazy will not gonna bring anything good to anyone so if he's really interested to trade bitcoin then maybe he should start to learn on how to do his first trade. Although we know its risky but frequent exposure on trading would provably result into good for him since he could learn a lot from his experience and learnings thru research also thru people discussions about this kind of activities.
To many people got victimized by their what so called friend friend saying that promise that their money or investment is safe with them, but it turns out nightmare to them since those people scam them.
