I think just tell them that cryptocurrency is a very easy and profitable side job, just sitting at home can make a profit. and maybe the drawback if the price drops must be patient until the price rises again.
That is actually exactly what we should be eradicating from people's minds. They think that you can simply sit at home doing nothing and make money from bitcoin. That might be the case if you have tons of bitcoins and you already have set sell orders and now you're just waiting for the price increase. Otherwise, you're not really going to make money by just sitting at home. People think bitcoin is a quick way to make you rich but it simply is not if you're not going to actively participate in the community and make money.
Because of that mindset, people backoff once they found out that it's actually not as easy as it looks like. It requires tons of research and no one in here is going to spoon feed you with all the information that you need. The research has to be done by you alone. You're lucky if you have an enthusiastic friend who doesn't mind sharing his knowledge of crypto but most of us doesn't have that type of friend.
