I couldn't agree more.
That's why there's always the option of managing other people's funds. That way, you're no longer risking your own money, but someone else's investments. For a steady income, you could also launch a subscription-based copy trading service or build a referral network.
I'm sorry but I don't agree with that. Managing other's funds is I believe a bigger responsibility because you not only lose money but you lose someone's trust and respect too. You can also face legal consequences by losing someone else's money. Infact it can be riskier to trade with someone else's money because the pressure of accountability is much higher.
But if you are a successful trader. I don't think you would need someone else's funds to trade yourself. But if you are considering taking loan from someone to trade and you are successful trader still you should take an amount that you are comfortable repaying because it is not guaranteed that a person is a good trader so he will earn money sometimes successful traders lose large amounts of money too.
