Telling someone to sell their property and invest in Bitcoin is a risky decision. You are saying that you are taking the risk of investing in Bitcoin and you are aware of it. I hope you have considered all the possible risks.
Telling someone to do so is risky indeed, but not because bitcoin is a risky asset, but because in this case one invests not his own money. Even if the investment is profitable (and I believe it will be, because I am sure bitcoin is going to rise in the future) one won't feel totally free to dispose of at his own discretion. He will feel obligated to consult about his actions and will be limited. In my opinion, such a situation is not preferable while making an investment.
