Do not lie to people about what crypto is just so they would not think of it as something not worthwhile. Rather explain eagerly. I did this so that my friend would not worry about my financial state and if he ends up becoming interested in bitcoin then I would be glad to continue teaching him.
Why is this looking irrelevant to me? I don't know why anyone in their right state of mind will want to lie for people to buy or invest in Bitcoin, it's not like they are going to gain something doing that rather they are only giving false hope which in my opinion can back fire if the market doesn't do as he said in the beginning or might turn out well for the person. So there is nothing to lie about to someone buying or investing in Bitcoin just to persuade them.
The only thing I can persuade someone to do is to make sure they back up their seed phrase and make sure their coins are been sent to their personal wallet. Those are the mistakes I know might back fire because I have experience a situation where a person bought a coin in his personal wallet and because he was still having access to his wallet through his phone, forgot to back up his wallet and when the phone got stolen, he lost access to his wallet and was sober the whole time.
