So I've told him that I'm not involved if he gets to Invest at this time because I know he'd panic over the volatiles of the bitcoin market since he doesn't have another source by which he can rely on earning income to process his financial needs. The choice is his to decide because if he had alternated his source of earning to bitcoin since I told him, the dividends of his bitcoin assets would had be reliable to him after much he may have made some profits from it. It'd had also served as means of savings and factor to encourage him to be economical with his luxury life which he doesn't have the potential to continuesly afford them
I'll avoid also accountability with these kind of people. If they're going to pass the responsibility to me or they'd make me feel guilty, I don't like that. You just did the right thing to tell that you're not accountable what will happen to his investment and you're not involvement whether he profits or not. In my experience, with these people, they're likely to blame you just for the volatility of Bitcoin but when they're in profit, they'd happy secretly and won't even credit you for helping them.
That's why I avoid talking to friends and relatives that I know their motives and attitudes towards something. If they can't take it on their own, they should better get away and stay off the market because no one is going to save them with their losses. I don't like people who likes to blame because they'd make you feel bad at all times and with little losses that they'd get, they want to make you refund it to them as soon as possible.
Otherwise, they're going to tell you that you shouldn't tell them what to invest or pushed you to invest where in fact that you've told them that you shouldn't blamed for their investment because they were the ones decided to invest and not you.
