That's not the point though. People are clearly misinterpreting what I said.
If you traded money from a relatively like I did, it was all but a pleasant experience. These people who don't know anything about trading or investing keep harassing you, "what are you buying now?", "I heard in the news that this or that stock went up, surely you are buying?", "hey, why are you short oil when they said stocks are declining?"
I've traded money from a relative for a month, and it freaked me out completely.
You know why people working in IT prefer not to help their relatives with IT problems? For the exact same reason. It's not because they treat those problems differently or that they find them more risky. It's because the people behind them have little idea about what it takes to manage those situations.
You made it sound like I considered money of stranger's of less value, which I don't. On the contrary, I would consider it to have more potential, because getting a small sum of money from a relative or friend is probably the best it's going to get. Getting a sum from a stranger who might know someone else or could help you get more money through his network or acquaintances, is a lot more interesting, so I would definitely treat it with the respect it deserves.
