It is not right to advise or force someone to invest. This can harm you. For example, if you advise someone to invest, if the Bitcoin market falls a few days later and his holdings are losing some money, he may panic and sell his holdings. He will blame you completely for his losses. If someone is willing to invest, then if he comes to you and asks for some advice, then you can present to him the basic knowledge about Bitcoin and the Bitcoin network system. And you can tell him that you can do more research and decide.
