I try as much as possible not to allow monetary issues to come between me and my friends, from my personal experience I wouldn't advice it. If your friend is a very good and experienced crypto trader then let him mentor you, guide you on how to become a professional trader, instead of trading on your behalf. You can not become a real trader if someone else is doing it for you, you can start with demo trading and gradually start to improve your skills before starting actual trading. What if he's making profits and is telling you that he's loosing your money, how will you know without understanding how trading works?
Various conveniences can be found in trading because several large trading platforms already have features that make it easier for people to trade as long as they have sufficient capital.
Of course in theory we can easily say that, but we certainly have another meaning that apart from needing money, knowledge needs to be prioritized rather than handing over money to other people to carry out trades. This is no different from enjoying the profits made by one's own efforts rather than getting big profits from the efforts made by other people.
