But the problem is that as OP shared, he has no intention of becoming a bitcoin trader in the near future . What he wants is to be able to make money from the market without spending time on it and relying on friends is the solution he is thinking of.
There are people who give their money to a fund manager the latter manages everything for them. This mindset seems wrong to me and hence I trade on my own. However certain people like it and they run it like that too, I am not aware of their profits but I would never advice someone to do that.
In case of the OP, this sounds very much like this group of people. My personal advice is always to learn about bitcoin and trade it on their own. If they are not doing that then they will lose money. I see the point of "not your keys not your coins" has been brought up. Indeed, these stubborn practices of handing over the onus of your own money on someone else's shoulders need to stop.
I understand why OP has come to question this. It’s obvious that he has not gone into trading and just think that trading is just easy to gain profits so if he will entrust his funds to his trusted friend, that will eventually become a successful trade and be in profits.
Reality is any trading activity won’t even guarantee profits even if the trader itself is good and reliable enough. That’s how risky trading is, which means he should learn trading on his own so he will develop his own knowledge and skills in trading, rather than relying on a trusted friend and yet in the end, the trade itself does not end well, so that only increase the risk on losing his funds. At least if he do that on his own, he may lose on his first trade but he’ll eventually learn his own lesson and becomes a better trader the next time he’ll trade.
