Ever since i introduced my friend to the DCA method of trading in btc he has been having some good turn up but he was asking me if i can loan him some money so he can add up to boost his staking so please guys how do i go about it should i give him or i shouldn't.
Never lend your money for investment purposes. Because in reality, investments should be well planned based on a person's financial situation. One cannot force themselves to invest with loans, whereas if you want, you can actually use your own money for investing as well.
Your friend should learn how to manage risks, especially regarding their finances. They should not become so obsessed with DCA that they do everything possible to continue doing it, even at the cost of neglecting their troubled finances.
